Micromacro entangled cat states could one day test quantum gravity

first_img Journal information: Physical Review Letters In order to extend quantum effects to the macroscopic level, physicists are working on creating entanglement between a macroscopic and microscopic system. This situation is very similar to that of the entanglement between the quantum state of the macroscopic cat and that of the microscopic decaying nucleus. So far, micro-macro entanglement has been experimentally demonstrated in optical systems, and is currently being pursued in other areas, such as electro-mechanical and opto-mechanical systems.In a new study published in Physical Review Letters, physicists Roohollah Ghobadi, et al., have proposed a method for generating optomechanical micro-macro entanglement. One of the most intriguing outcomes of bringing quantum effects to the macroscopic level using this approach is that it could allow researchers to test for wave function collapse due to quantum gravity, which is predicted to occur on a much shorter timescale than wave function collapse due to environmentally induced decoherence.”Our proposal allows for observation of the genuine macroscopic superposition of massive objects,” Ghobadi told Phys.org. “It also looks promising to test some collapse models.”The proposed method involves storing one component of an entangled state of light (consisting of just one or a few photons) in a mechanical resonator (consisting of billions of atoms). During this process, the initial microscopic entangled state of photons is amplified with a strong coherent beam, the photons are converted into phonons, and then the entangled states are retrieved. This approach makes it possible to create optomechanical “cat states,” in which the quantum states of the photons and phonons are in superposition. The researchers write that the scheme is realizable with current technology, and if realized, would be the second demonstration ever of optomechanical entanglement. To test proposals for quantum gravity-induced wave function collapse, future experiments could be performed that compare the collapse time (estimated to be on the order of microseconds) to the collapse time of environmentally induced decoherence (on the order of milliseconds).”It is interesting to do the proposed experiment for different masses in order to distinguish the decoherence due to a collapse model from conventional environmentally induced decoherence,” said coauthor Christoph Simon, Physics Professor at the University of Calgary.In addition, by varying other factors such as the amplification and the number of phonons, researchers could use this method to look for other types of deviations from quantum physics in this little-explored regime of micro-macro entanglement and superposition.”One possible direction is to apply the method proposed here to create cat states in other systems,” Ghobadi said. “It is also interesting to look at its application in quantum information processing.” (Phys.org) —In Schrödinger’s famous thought experiment, a cat’s quantum state becomes entangled with the quantum state of a decaying nucleus, resulting in the odd situation that the cat is both alive and dead at the same time. The thought experiment was originally intended to convey the absurdity of applying quantum mechanics to macroscopic objects, but recently physicists have been questioning whether “quantum” effects such as entanglement and superposition may apply on all scales.

Study shows one reason why pigeons so rarely crash

first_img More information: Pigeons trade efficiency for stability in response to level of challenge during confined flight, C. David Williams, PNAS, DOI: 10.1073/pnas.1407298112 AbstractIndividuals traversing challenging obstacles are faced with a decision: they can adopt traversal strategies that minimally disrupt their normal locomotion patterns or they can adopt strategies that substantially alter their gait, conferring new advantages and disadvantages. We flew pigeons (Columba livia) through an array of vertical obstacles in a flight arena, presenting them with this choice. The pigeons selected either a strategy involving only a slight pause in the normal wing beat cycle, or a wings-folded posture granting reduced efficiency but greater stability should a misjudgment lead to collision. The more stable but less efficient flight strategy was not used to traverse easy obstacles with wide gaps for passage but came to dominate the postures used as obstacle challenge increased with narrower gaps and there was a greater chance of a collision. These results indicate that birds weigh potential obstacle negotiation strategies and estimate task difficulty during locomotor pattern selection.

Wilson/Wikipedia/CC BY-SA 2.5 © 2015 Phys.org City dwellers know that pigeons are some of the best flyers around, unlike robins and other birds, pigeons rarely collide with cars, buildings, trees or any other obstacle. That skill has not gone unnoticed—scientists and engineers have been working for years to duplicate their abilities. In this new effort, Williams and Biewener taught some of their tamed specimens to fly through a corridor to get to a meal, then introduced obstacles and high speed cameras to find out how it is that the birds are so good at avoiding objects in their path.The obstacles were plastic pipes, placed vertically some distance apart from one another. To pass between the pipes, the birds had to scrunch themselves a bit, but how they did so, the researchers found, depended on how far apart the pipes were. They noted that when the pipes were at least a half a wing length apart, the birds lifted their wings as if to flap as they approached the obstacle, but then held them steady, above their heads as they passed between the pipes, then flapped down as soon as they were through—a technique that led to very little loss of altitude, which meant it was quite efficient. But if the pipes were moved closer together, they pulled their wings into their body, a less efficient approach, but one much less likely to result in wing damage. To make sure the first approach was not merely coincident based on where the wings were when the birds arrived at the obstacle, the researchers filmed them multiple times, finding the same result each time.Because the birds used two different techniques for allowing them safe passage through the pipe obstacles, based on what they observed as they approached, the researchers believe that choosing which technique to use was a deliberate act, which meant the birds somehow made a choice of which technique to use, just before they passed through—very impressive, especially when noting that birds, except for some such as crows or magpies, are not generally known for their smarts.

Curiosity rover finds possible evidence of ancient explosive volcanoes on Mars

Apart from any fair dealing for the purpose of private study or research, no part may be reproduced without the written permission. The content is provided for information purposes only. (Phys.org)—A large team of researchers from across the U.S. studying data sent back from Mars by the Curiosity rover has found evidence of tridymite, a type of mineral associated with explosive volcanoes here on Earth. In their paper published in Proceedings of the National Academy of Sciences, the team describes how the rover found the sample, the testing it underwent, and why it might lead to rethinking the early history of the Red planet. More information: Richard V. Morris et al. Silicic volcanism on Mars evidenced by tridymite in high-SiOsedimentary rock at Gale crater, Proceedings of the National Academy of Sciences (2016). DOI: 10.1073/pnas.1607098113AbstractTridymite, a low-pressure, high-temperature (>870 °C) SiO2 polymorph, was detected in a drill sample of laminated mudstone (Buckskin) at Marias Pass in Gale crater, Mars, by the Chemistry and Mineralogy X-ray diffraction instrument onboard the Mars Science Laboratory rover Curiosity. The tridymitic mudstone has ∼40 wt.% crystalline and ∼60 wt.% X-ray amorphous material and a bulk composition with ∼74 wt.% SiO2 (Alpha Particle X-Ray Spectrometer analysis). Plagioclase (∼17 wt.% of bulk sample), tridymite (∼14 wt.%), sanidine (∼3 wt.%), cation-deficient magnetite (∼3 wt.%), cristobalite (∼2 wt.%), and anhydrite (∼1 wt.%) are the mudstone crystalline minerals. Amorphous material is silica-rich (∼39 wt.% opal-A and/or high-SiO2 glass and opal-CT), volatile-bearing (16 wt.% mixed cation sulfates, phosphates, and chlorides−perchlorates−chlorates), and has minor TiO2 and Fe2O3T oxides (∼5 wt.%). Rietveld refinement yielded a monoclinic structural model for a well-crystalline tridymite, consistent with high formation temperatures. Terrestrial tridymite is commonly associated with silicic volcanism, and detritus from such volcanism in a “Lake Gale” catchment environment can account for Buckskin’s tridymite, cristobalite, feldspar, and any residual high-SiO2 glass. These cogenetic detrital phases are possibly sourced from the Gale crater wall/rim/central peak. Opaline silica could form during diagenesis from high-SiO2 glass, as amorphous precipitated silica, or as a residue of acidic leaching in the sediment source region or at Marias Pass. The amorphous mixed-cation salts and oxides and possibly the crystalline magnetite (otherwise detrital) are primary precipitates and/or their diagenesis products derived from multiple infiltrations of aqueous solutions having variable compositions, temperatures, and acidities. Anhydrite is post lithification fracture/vein fill. To date, planetary scientists believe that the geological history of Mars has been very tame compared to our own home planet—this is, they believe, because Mars does not have shifting plates that lead to big earthquakes and explosive volcanoes. Evidence of volcanoes on that planet to date has shown them to be of the steady flowing type such as those that led to the creation of the Hawaiian Islands—they form due to melting hot mantel plumes just below the surface. But now, a mineral find might mean scientists will have to rethink the ancient history of Mars.The Curiosity rover has been rolling around in Gale crater since 2014, and last year it began digging and studying samples from an area known as Marias Pass. The research team noted that the makeup of the rocks there appeared to suggest silica, so they subjected them to X-ray analysis. That showed the samples to have a very high level of tridymite, which was both surprising and thought provoking because it conflicted so sharply with the history that has been written for the planet—they suggest it appears likely that the mineral was created somewhere else on the planet and was carried to the crater basin. This is because prior research has suggested parts of the basin were once filled with water—that Martian lake would have been filled by streams and rivers coming from distant places bringing with them and depositing sediments, some of which could have been material ejected or formed by explosive volcanoes. But if Mars did have such volcanoes, the team wonders, how did they form in the absence of plate tectonics?The findings by the team and their theories are likely just the first stage of what will be many projects aimed at reevaluating Mars’ history, or looking for ways that tridymite might be created without the intense heat of a violent volcanic eruption.center_img Citation: Curiosity rover finds possible evidence of ancient explosive volcanoes on Mars (2016, June 14) retrieved 18 August 2019 from https://phys.org/news/2016-06-curiosity-rover-evidence-ancient-explosive.html Journal information: Proceedings of the National Academy of Sciences © 2016 Phys.org Explore furtherlast_img read more

It will open with Also Read – ‘Playing Jojo was emotionally exhausting’Atmakatha, a two-hour play directed by Vinay Sharma, featuring former Bollywood actor Kulbhushan Kharbanda. It will mark the actor’s return to the stage, Allana said. ‘The wider variety of plays this year has allowed us to package them into categories. The ‘Manto section’ has six plays adapted from stories by Manto and the section on Shakespeare will explore the ‘inter-cultural influence on the dramatist’ with seven productions,’ Allana said, adding: ‘The focus will be on popular theatre that evolved from the Parsi form of theatre in the second half of 19th century.’ The 450 entries from which 87 were shortlisted were from across regions and genres that were not always ‘dependent on the government for support’.

The Shakespeare panorama will play host to the likes of indigenous improvisations of King Lear, a solo performance from Turkmenistan, an Assamese adaptation of Julius Caeser, a Hindi makeover of Twelfth Night, Piya Behroopia that played at the Globe Theatre in London last season, Footsbarn Theatre’s Indian Tempest as physical theatre. Wendy Jehlen of the US will present excerpts from Hamlet, Macbeth, Othello and Titus Andronicus in a choreographed non-verbal piece as The Knocking Within.A Malayalee adaptation, Yamadoothu: After the Death of Othello in Malayalam from Kerala, based on Shakespeare’s Othello will also be staged. Pointing to the trends in Indian contemporary theatre, Amal Allana said: ‘the trend to go back to traditional forms of theatre has waned’.‘We don’t have to go back to folk theatre and traditional theatre to sustain contemporary theatre. Plays are being staged as performances and devised scripts. There is more exchange and effort between theatre people because of greater a sense of participation and lack of original scripts,’ Allana said.She said: ‘The complexity of new theatre has brought in wake more non-verbal plays and physical theatre’. NSD director Anuradha Kapur said ‘there was a flowering of another kind of script that were meant to be read. We are reading scripts and performing them as well’.

Aggressive driving a reflection of surrounding culture

first_imgAggressive driving behaviour is a reflection of a person’s surrounding culture, both on the road and on a broader social level, says a study.The findings suggest that some countries and cultures may be more susceptible to aggressive or competitive driving behaviours due to their social environment, and that improvements in that arena would also be seen in driving behaviour.“The choice to be competitive versus cooperative always starts with culture, by the influences around us and the way other people behave, ‘said one of the researchers Haizhong Wang, assistant professor of transportation engineering at Oregon State University in the US.  Also Read – ‘Playing Jojo was emotionally exhausting’“And it’s clear there’s a role for education and experience, where studies have shown the value of young drivers participating in driver education programmes and receiving positive guidance from their parents and peers,” Wang noted.The study also implies that different social conditions might ultimately translate into better drivers.However, these dangerous behaviours are becoming a worldwide phenomenon of almost epidemic proportions partly as a reaction to overcrowded road networks, the researchers said. Also Read – Leslie doing new comedy special with NetflixThe findings, published in the journal Procedia Engineering, showed that such behaviour is more pronounced in men than in women.The research was done with drivers in China where competitive driving is very common. The problems in China as it becomes increasingly crowded with drivers, however, reflect similar concerns at varying levels around the world, Wang said. In this analysis, the researchers concluded that drivers in congested situations generally believed that the chaotic traffic state was responsible for their competitive behaviour and they had no option other than to compete for space, the right-of-way, and gain advantages through speed and spacing.In simple terms, it was right and proper that they should try to keep up with or get ahead of traffic; that was the example being set for them, and they drove that way because everyone else did.However, the study also suggested that “personality traits draw on and are influenced by aspects of one’s social environment.” It is prevalent in India too where the surroundings play an important part.last_img read more

Register Now » January 25, 2011 Lexmark GenesisPhoto © David JohnsonThe all-in-one business printer/fax machine/scanner is becoming a work of art.The touch-activated Lexmark Genesis pushes the bounds of small-business imaging both in performance and good looks. The 15-inch-by-16-inch Genesis is about half the size of an average all-in-one printer. It holds pages vertically, so it can scan both sides of a document in a zippy three seconds. And the unit, which connects directly to the web, is controlled via a slick 4.3-inch touch-activated screen that’s about the size of an iPhone.Performance is solid, with high quality and decent speed: 33 pages per minute in black and white, and 30 pages in color. But what really makes the Genesis unique is its design. Its attractive black form factor looks more like a high-end audio component than a printer, yet it doesn’t compromise its image quality or functionality for light business use.The Genesis is far from perfect. The vertical page layout can be clumsy when lots of copies are required, and it is not a battle-tested concept for printers. (Who knows how hinges, hardware and electronics will hold up after years in the office?) And then there is the cost: $400, in a world where $60 buys a lot of printer.But for folks who want their printers to make a statement, the Genesis is an intriguing option.last_img read more

Three Tips for Using Public WiFi Safely

first_img In an era of laptops, smartphones and mushrooming Wi-Fi networks, we can get online nearly anywhere. But we often connect without considering the potential perils.Sensitive information you transmit over Wi-Fi can be literally “sniffed” from the airwaves by a nearby snoop using readily available software and equipment. What’s more, hackers could trick you into connecting to their computer by making it appear to be a legitimate Wi-Fi hotspot.Despite these risks, it’s relatively easy and inexpensive to surf safely. Here are three tips for securely using Wi-Fi networks when you’re on-the-go, doing work in hotels, airports, cafés and other public places.1. Avoid automatically connecting to Wi-Fi hotspots.It can be tempting to quickly jump online using one of the 1.4 million public Wi-Fi networks now active in the world. But you could unwittingly connect to a rogue hotspot set up by a crook to gather sensitive information transmitted by unsuspecting users like you.Industry group Wi-Fi Alliance recommends that Web users carefully select which, if any, public network they access rather than allow their device to connect automatically. It also recommends choosing only hotspots that use security technologies known as Wi-Fi Protected Access version two, or WPA2, which are stronger than the older WPA and Wired Equivalent Privacy (WEP) technologies. A network’s security system is displayed in the box where you enter a password to connect.Related: What to Do If Your Business Gets Hacked 2. Make sure sensitive websites you use encrypt data you send and receive. Sending and receiving information on unsecured public wireless networks can be like shouting in a crowded room, says Maxim Weinstein, executive director of StopBadware, a Cambridge, Mass., nonprofit group that fights malicious websites. “Unless you’re talking in code, it’s no secret to anyone who’s listening.”Fortunately, most websites that handle sensitive information use encryption technology known as Secure Sockets Layer (SSL) to turn readable text into a mash of digital gibberish. You know SSL is in place if you see “https” in the address bar. It is almost always at work when you’re making a purchase or banking online.Related: How to Protect Android Smartphones From Cyber AttacksMany communication services, such as Google’s Gmail, Microsoft’s Hotmail and Facebook, also use SSL to keep your private communications safe from eavesdroppers. Some services, such as Gmail, use HTTPS by default at all times, but Facebook and others require you to turn the technology on.To activate it on Facebook, click on the down arrow in the upper right corner and select Account Settings. In the left column, click Security and enable Secure Browsing.3. Install and use VPN software on your device to encrypt your Internet activity. “Virtual private network” software is a must-have for road warriors who regularly transmit sensitive data over public Wi-Fi networks. VPN software creates an encrypted tunnel through which your data flows as it traverses the Internet. Employees at many large companies already use VPNs on business trips to protect valuable corporate information, and small companies would be wise to follow suit.If you don’t have an information-technology department that can set up a VPN for you, consider using one of the personal VPNs now on the market. Options include PrivateWiFi from startup Private Communication Corp. (Windows and Mac, $9.95 a month or $84.95 a year; three-day free trial); Anonymizer Universal (Windows, Mac, iPhone and iPad, $79.99 a year; 14-day free trial); and VPN4ALL (Windows and Mac $9.95-$19.95 a month, depending on amount of data use; iPhone, iPad, Android, Windows Mobile and tablets, $5.95 a month).Related: What Technologies Banks Should Be Using to Keep Your Money SafeOpenVPN Technologies, keeper of the open-source technology behind some of these software products, sells a hosted VPN service specifically to small businesses called PrivateTunnel (Windows and Mac, price based on amount of data transferred).Another thing to consider: putting up a firewall to block strangers seeking access to your computer. Firewalls are typically provided by modern operating systems and are on by default. To make sure yours is active on a Windows PC, review Microsoft’s directions based on your operating system version. On Macs, open System Preferences and click Security & Privacy and then Firewall.You also can avoid Wi-Fi networks altogether and go online using a cellular connection from a wireless carrier, which use encryption when transferring data, albeit at a significant cost. Plan to pay for a large or unlimited data plan for a mobile device. For your laptop, you’ll need a special device that plugs into the side and a monthly service plan. Verizon and AT&T can charge $50 to $60 a month for 5 GB.  Free Webinar | Sept 5: Tips and Tools for Making Progress Toward Important Goals Opinions expressed by Entrepreneur contributors are their own.

This Site Wants to Help You Make Startup Friends While You Travel

first_img Free Webinar | Sept. 9: The Entrepreneur’s Playbook for Going Global 4 min read Say you’re visiting a new city to meet a client or scout out a business location. In the past, you might have spent hours searching your network, trying to find someone to show you the lay of the land. But with the free service Startuptravels, the work is done for you with a few clicks.  That was the impetus for Anders Hasselstrøm’s project. The Copenhagen-based tech entrepreneur often traveled to Scotland on business. Last summer he seized on the idea that there was potential to up the value of those visits. “I was traveling back and forth twice a month, and I realized I should connect with entrepreneurs while I was spending so much time there,” he says. Unfortunately, Hasselstrøm couldn’t find a simple, online way to do that. “I reached out to other entrepreneurs I knew and found they were having the same issue.” His goal was to develop a service that connected visiting entrepreneurs with fellow businesspeople based in the city. The traveler could ask to grab a coffee, request an introduction to another entrepreneur, or ask for help finding local vendors or resources for a project. He or she could even barter for office space or a place to stay during the trip.To further hone the idea, Hasselstrøm connected with developers Henrik Haugbølle and Rasmus Frandsen. The three surveyed every other entrepreneur they knew—more than 250 in all—to find out their travel patterns and needs. Among the suggestions for the network was to base users’ profiles on their LinkedIn page. In practice, Startuptravels users register on the site using their LinkedIn login, and their profiles, work histories and other details automatically transfer over. The info can then be modified with useful tags like “Early Entrepreneur” and “Investor.” As soon as someone decides where and when to travel, he or she can look up locals to meet during specific dates. As more people join the site, Startuptravels’ algorithm will weed through the listings to suggest entrepreneurs with similar backgrounds and interests. Still in beta since launching in October, Startuptravels now counts nearly 3,000 active users in 120 countries. Hasselstrøm’s reliance on a community of developers to build the site saved costs and time, and created a built-in set of evangelists to promote the service. “Our co-developers were the guys who fit the archetype of our website’s persona,” Hasselstrøm says. “They are power users who are willing to give their time, office space and perhaps a spare couch to make the service valuable to fellow entrepreneurs.” Why the name Startuptravels instead of something with broader appeal? Hasselstrøm says the point was to make the service relevant to entrepreneurs at a specific stage in their careers. It also doesn’t hurt that the startup community is, by his thinking, the cool place to be right now. “Our network wouldn’t have been as valuable five or even two years ago, but today the startup economy is booming worldwide,” he says. “Startup people are the new rock stars, so now it’s not uncommon for people to identify as such. Startups now have much more value, not only in the number of people who are involved in [them], but in the respect for the word startup itself.”  March 11, 2015 Register Now » Growing a business sometimes requires thinking outside the box.

Elon Musks SpaceX Plans Hyperloop Contest

first_img Hear from Polar Explorers, ultra marathoners, authors, artists and a range of other unique personalities to better understand the traits that make excellence possible. 3 min read June 15, 2015 Listen Now The SpaceX rocket company announced something completely different on Monday: a Hyperloop pod competition that would follow up on a high-speed transit concept laid out by the company’s billionaire founder, Elon Musk.The contest would reach its climax next June with pod races at a roughly mile-long (1.6-kilometer-long) Hyperloop test track that will be built next to SpaceX’s headquarters in Hawthorne, California, according to documents obtained by NBC News.Musk conceived of the Hyperloop in 2013 as a network of pneumatic tubes through which aerodynamically designed passenger pods could travel at speeds of up to 760 mph (1,220 kilometers per hour). He suggested that a trip between San Francisco and Los Angeles could take a mere 35 minutes, for a price of $20 one-way.The contest announced Monday marks the most concrete step Musk has taken to turn the multibillion-dollar Hyperloop into a reality.Two years ago, Musk said he couldn’t get involved in building the Hyperloop, due to the crush of his duties as CEO of SpaceX and Tesla Motors. Since then, several other groups have tried to push the concept forward. One venture, called Hyperloop Transportation Technologies, is working on a deal to build its own 5-mile test track in central California. Another startup, Hyperloop Technologies, is building hardware.Epic day! Building the hardware and tech to help make Hyperloop a reality. pic.twitter.com/NJtxFU0Ugf— HyperloopTech (@HyperloopTech) June 12, 2015″We are excited that a handful of private companies have chosen to pursue this effort,” SpaceX said in a statement. “Neither SpaceX nor Elon Musk is affiliated with any Hyperloop companies. While we are not developing a commercial Hyperloop ourselves, we are interested in helping to accelerate development of a functional Hyperloop prototype.”Hence the fast-track pod competition.SpaceX said the contest would be geared toward university students and independent engineering teams. Their task would be to design and build half-scale passenger pods, in accordance with design specifications that are to be released in August.Teams have to signal their formal intent to compete by Sept. 15. A “design weekend” would be held at Texas A&M University on Jan. 9, 2016. During that event, the teams’ proposed designs would be vetted by a panel of experts from SpaceX, Tesla and universities.The finished pods would be pitted against each other on the test track in June 2016. The track would be less than full scale, with an inner diameter of 4 to 5 feet (1 to 1.5 meters). No humans would be allowed on the pods during the competition, SpaceX said.”The knowledge gained here will continue to be open-sourced,” SpaceX said. “Break a pod!”SpaceX updated its Hyperloop Web site with information about the competition, and kicked its @Hyperloop Twitter account into gear on Monday.Word of the contest follows through on Musk’s musings about the Hyperloop in January, when he told attendees at the Texas Transportation Forum that he was thinking about building a test track. (At that event, however, Musk said the track would “most likely” be built in Texas.) He said a Hyperloop test program could be modeled after the Formula SAE student competition for automobile design.”People could compete, say, who could make the pod go the fastest, and maybe compete on other dimensions,” Musk said in January. “I think that could be pretty fun.” This story originally appeared on CNBC How Success Happenslast_img read more
