Braiding may be key to using time crystals in quantum computing

first_imgThe braiding method in the new study consists of a four-step process that involves slowly tuning the parameters of the system that generates the Majorana time crystals. In each step, the 0 and π modes are shifted, so that at the end of the entire process, the sequence of transformations results in one complete braiding operation that resets the system to its initial configuration. In the future, time crystals may lead to new ways to perform certain quantum computational tasks. With this goal in mind, the physicists also showed that their quantum control protocol can be applied to time crystals to generate “magic states,” which are a basic requirement for quantum computing. “Braiding time crystals is potentially useful for quantum computation because we exploit their time-domain features and thus obtain more qubits for encoding information, and hence achieve savings in hardware,” Gong said.In the future, the physicists plan to further explore the possibilities of braiding time crystals. For one thing, they expect that extending braiding from one superconducting wire to an array of wires may allow them to simulate more intricate braiding processes.”Given that we have now shown how the time dimension can be used as a resource for performing quantum computation, one future direction we have in mind will be to explore the possibility of storing and manipulating information with even fewer physical resources by enlarging the system in the time direction and by making use of more Majorana modes in periodically driven quantum wires,” Gong said. “As a long-term goal, we plan to use this idea to design a robust quantum computer architecture with an optimal amount of resources—that is, one that is relatively small in physical size, but does not take a very long time to operate.” Braiding time crystals.

Now in a new study, physicists Raditya Weda Bomantara and Jiangbin Gong at the National University of Singapore have taken some of the first steps toward showing exactly how that might be done. They theoretically demonstrate that, by braiding two different modes of time crystals, it’s possible to generate the states that are necessary to perform universal quantum computation.

DOI: 10.1103/PhysRevLett.120.230405Also at arXiv:1712.09243 [quant-ph] Time crystals have attracted the attention of physicists since the concept was first proposed by Frank Wilczek in 2012. Five years later, in 2017, time crystals were experimentally realized for the first time. Just as ordinary crystals are characterized by their repeating patterns in space, time crystals—which are always moving—have the unique feature that their motion exhibits repeating patterns in time. To realize a time crystal, a periodically driven laser sets the particles in a superconducting loop in motion. When the system is manipulated in a precise way, the particles’ motion collectively synchronizes in a periodic manner, resulting in a time crystal.In the new study, Bomantara and Gong have developed a method for harnessing the unique properties of time crystals for quantum computing that is based on braiding. To do this, they turned to a particular type of time crystal called a Majorana time crystal, whose name comes from the way it’s created, which is from the quantum coherence between two types of Majorana edge modes (0 and π) in a superconducting chain. The reason for choosing Majorana time crystals is that they share similarities with a type of quasiparticle called non-Abelian anyons, which can be braided and have recently been considered as a potential component of a topological quantum computer. By making use of this connection to non-Abelian anyons, the physicists showed that it’s possible to mimic non-Abelian braiding in Majorana time crystals.”Loosely speaking, braiding refers to exchanging the location of two particles,” Gong told Phys.org. “In order to carry out this exchange, the particles are to be systematically moved around each other in such a way that if we draw the paths traversed by the two particles in spacetime, they form a braid. We know in real life that there are different types of braids, and that converting one braid to another requires certain operations that nature cannot do by itself. As a result, by storing information in these different types of braids, we can manipulate this information (hence performing quantum computation) by changing one type of braid to another (hence called braiding) without worrying that some external disturbance may destroy them.” Explore further This document is subject to copyright.

BJP divided over Raje fate Cong goes for jugular

first_imgA party insider told Millennium Post that senior leaders are in a fix on whether to retain or remove Raje. Prime Minister Narendra Modi and party president Amit Shah will take a final call on the matter only after Union Finance Minister Arun Jaitley is back from his US trip.The BJP, which has been defending Raje, was on the back foot when the Congress flashed signed documents (dated August 18, 2011) by Raje, favouring Modi, in a press conference recently. The document signed by Raje and filed by Modi’s immigration attorney Ghersons with the UK authorities endorsed his claim of facing political persecution in India.  Also Read – Need to understand why law graduate’s natural choice is not legal profession: CJIHence, he deserved to be given a resident status. The conclusion of Raje’s letter was “she was making the statement on the condition that it wouldn’t be known to the Indian authorities.”According to sources, Raje has already admitted to senior party leaders in Delhi that it is her signature, but insisted that she has done nothing wrong as per Indian law. However, a section of party leaders refused to buy Raje’s theory, suggesting that she should step down from the CM’s post in  the party’s interest, especially when crucial state elections are round the corner. Also Read – Health remains key challenge in India’s development: KovindSensing that things were going haywire and realising that she was facing the worst crisis in her political career, Raje on Thursday met party MLAs in Jaipur to flaunt her support and popularity before the Union ministers. On Thursday morning, she met over 20 BJP leaders – her Cabinet colleagues, MLAs and BJP functionaries –at her official residence, where a section of media were heckled by security officers.Many feel that the meeting was part of a pressure tactic on BJP leaders in Delhi, indicating the kind of support she enjoys from the party’s Rajasthan unit. “Going by the situation, if something (bad) happens, then there are possibilities that she might float her own party,” said the party insider. However, Rajasthan Health Minister Rajendra Rathore has ruled out Raje’s resignation, saying: “There are media speculations that the Central leadership will ask her to resign. But all I want to say is that she is not going to resign.”Meanwhile, the Congress intensified its protest against Raje. The CPI-M and the Aam Aadmi Party (AAP), too, have demanded her immediate resignation. “Vasundhara Raje knows that the signature is hers and she has never denied it. At this late stage, I don’t think anybody will buy if she comes up and says that they are forged or falsified. I hope BJP will also not buy that argument,” said Congress leader Sachin Pilot.He added: “Unfortunately for BJP, they have to realise the inescapable truth is that she has broken the law. She has transgressed the Indian law knowingly and the flying statement, which shows that she was trying to help Lalit Modi get travel documents, is in violation of law and by no means the BJP can continue to defend the indefensible.” “Where is the zero tolerance to corruption, Mr Prime Minister,” Pilot questioned.last_img read more

Bitcoin The Swindle of the Century

first_imgSeptember 7, 2018 The frenzy around Bitcoin is at a fever pitch, and the reasons are obvious. Its value has skyrocketed over the past year, making millionaires out of early adopters. In its wake, thousands of would-be investors and coin creators are getting in on the action.Related: 6 Cryptocurrencies You Should Know About (and None of Them Are Bitcoin)A quick primer for the uninitiated: Bitcoin is the most well-known and highly regarded of digital assets known as cryptocurrency. It’s presented as an alternative to traditional paper money, with speculative investors buying and selling fractional amounts of Bitcoins (which, as of this writing, are valued at over $6,000 per coin, way down from last December’s high of $19,783) with hopes that their value will rise. Its blockchain-backed anonymity and rocketing valuations have inspired a mass of imitators, each hoping to be the one that truly breaks through and replaces traditional money.For such a recent phenomenon, it may surprise some to learn that Bitcoin has existed since January 2009, created by a (possibly fake) Japanese developer named Satoshi Nakamoto. The dubious reality of its creator is appropriate for reasons I’ll get into later. Whether Nakamoto is an actual person, it’s completely true that “his” creation has dictated the conversation about the future of money and investing in the post-2009 crash era.Possibly the most impressive thing about crypto is how heavily major banks, accounting firms and even consumer corporations have bought into the craze in the near decade since. These big-name endorsements certainly make Bitcoin and other cryptocurrencies seem like a sure bet, but a cursory look beneath the surface reveals a lot of false promises and hype, with a need to dig a little deeper in order to see the real benefit of the crypto craze.Related: Why You Can’t Afford to Ignore Cryptocurrencies and Blockchain AnymoreThe BS of BitcoinIt’s not only the idea that Bitcoin will replace the existing currency system that’s extremely questionable. The entire idea of investing in cryptocurrency is where the real swindle happens.Investors, probably more so than any other group of people, are in love with the idea of getting in on the next big thing before it blows up. This isn’t breaking news: It’s how our money’s made. From VC to armchair investors, the idea is to buy in when prices are low and sell when they are high. So, it’s only natural that an unregulated and complex field like crypto attracts a lot of excitement for a certain type of investor, maybe someone who’s not as money-savvy but has caught on to the transformative power of the internet. The online aspect only democratizes it further: When anyone can buy in, anyone can profit.Which is where things get troubling. At the heart of it, cryptocurrency is a fraud. We’ve all been sold on Bitcoin as the official future currency of the internet, its evangelists painting a picture of a world where our spending is safely anonymized and no longer subject to the whims of international bankers and governments. A number of retailers have bought in as well, meaning Bitcoin can buy you anything from a hotel room to pizza delivery. Sounds great, sure, but at its essence, crypto has proven to be something else entirely.It’s not a true medium of exchange the way that government bank-backed paper money is. Bitcoin is an asset, and a particularly dangerous one to drop any amount of your investment money into. While it can be exchanged for goods, these transactions amount to barter deals with opportunistic retailers who are likely more eager for the publicity that comes with announcing they’ll accept Bitcoin. You don’t have to take my word for it: No less an authority than JPMorgan CEO Jamie Dimon has identified crypto as a bubble just waiting to bust. When that does happen, good luck paying for your pizza with whatever’s left.Even outside of the volatility of the currencies themselves, that Wild West atmosphere has proven a fertile ground for scammers. Old fashioned Ponzi schemes have gotten a 21st-century facelift thanks to criminals taking advantage of the Bitcoin craze, collecting funds for Initial Coin Offerings (ICOs) that never materialize. Fittingly for a currency that got its start abetting anonymous drug and weapons deals on dark web trading posts, unscrupulous operators have flocked to Bitcoin as their latest medium for ripping off the uninitiated. Consider yourself warned.Related: How Digital Wallets and Mobile Payments Are Evolving and What It Means for YouThe real benefitWhile Bitcoin as an investment is radioactive and not to be touched, it’s not the case that the whole cryptocurrency movement hasn’t created something of real benefit. The dangerous part of Bitcoin is in the unpredictability of the human element in the form of deceptive labeling and scams. The technology underpinning it all, free of hype and deceptions, is surprisingly trustworthy.The “crypto” in cryptocurrency comes from cryptography: the encryption technology that makes bitcoin transactions secure. Not only that, but all secure online activity is safe through the use of encrypted lines of code that can’t be broken by third parties. The encrypted ledger of Bitcoin transactions, known as blockchain, represents the safest data transfer medium ever created online. Burying your gold coins in the backyard was never this secure.The blockchain works because it isn’t stored on one central server: To alter its code would mean compromising a number of machines across a wide network, a near-impossible task for even the craftiest hacker. This level of security in transactions makes blockchain useful not only for ethereal assets like cryptocurrencies but real-money movement by banks and individuals alike.Once the Bitcoin craze blows away, we’ll be left with a truly transformative tool: a new, safe way to conduct business online. The evangelists weren’t completely wrong, only misguided. The bitcoins themselves won’t be changing our world, but the blockchain built to host them absolutely will.
