The phrase was coined in … A: It depends on what you think is a big deal. part may be reproduced without the written permission. Whether that will happen or not, nobody is really sure. But people are kind of gearing up, figuring the technology will mature, and they want to be ready. William Oliver of MIT compared the feat to the first successful flight by the Wright brothers. X-ray diffraction reveals details inside mummies without having to open them up, Physicist creates N95-type respirators using cotton candy machine, Springer Nature announces plan for open access publishing of research papers, Amateur astronomer Alberto Caballero finds possible source of Wow! In quantum computing, quantum supremacy is the goal of demonstrating that a programmable quantum device can solve a problem that no classical computer can solve in any feasible amount of time (irrespective of the usefulness of the problem). A: I suggested this term thinking we should take note that something kind of special is happening in the history of technology. Still, Google's success is a noteworthy steppingstone on what will probably be a long and winding road to quantum supremacy, Preskill said. But it's actually not so crazy to say that in the future, we might have a quantum internet which sends quantum information around because that could have advantages for encryption. Science X Daily and the Weekly Email Newsletter are free features that allow you to receive your favorite sci-tech news updates in your email inbox. "It won't change anything overnight, but it is significant that quantum computers are now at the stage that at least in some arena, they can outperform the best computers on Earth," he said. or. It seems unlikely that you will want to do your email on a quantum computer. Presumably, both of these will continue to happen. A: Based on our current understanding, I think quantum computers will have very specialized applications. "It is what the event represented, rather than what it practically accomplished, that was paramount," he wrote in a commentary that accompanied the study. Google has reached a milestone in computing by achieving "quantum supremacy." Q: How is a quantum computer different from a conventional computer? They try to put that on the computer, but when the molecule gets big it's just too hard because quantum mechanics is really important in a molecule, and you just can't describe what it is doing in terms of ordinary bits. Google has this machine, but whether it can do anything useful that anybody cares about over the next few years—nobody knows. We are in an era where we have this powerful device and don't know what to do with it. Your opinions are important to us. By using our site, you acknowledge that you have read and understand our Privacy Policy It is very hard to eavesdrop on information that is encoded in quantum states. Apart from any fair dealing for the purpose of private study or research, no It could help with the development of new pharmaceuticals, new energy sources, new ways to collect solar power, and new materials. Q: What led you to coin the phrase "quantum supremacy" in 2012? “Quantum computing is still in its infancy, but this transformative achievement … A: It could be decades, but nobody can say for sure. Using the company's state-of-the-art quantum computer, called Sycamore, Google has claimed "quantum supremacy" over the most … The Google AI Quantum team is … Google says that its 54-qubit Sycamore processor was able to perform a calculation in 200 seconds that would have taken the world’s most powerful supercomputer 10,000 years. officially announced that it’s achieved quantum supremacy in a new article published in the scientific journal Nature This document is subject to copyright. We have to experiment with it and try different things. This is more of a metaphor than a technically accurate statement, but in a quantum computer you have a qubit, which can be a 0 and 1 at the same time. Indeed, IBM, which has its own 53-qubit quantum computer, prefers a higher threshold for quantum supremacy, which explains its argument that Google has not yet reached the milestone. I understand that concern. A: The language that classical computers speak is all about manipulating strings of zeros and ones, but the language of quantum physics is quite different. I don't think anybody has done anything with a quantum computer so far that you couldn't do much better with existing digital, classical computers. That might be quite a ways down the road, but it's part of what gets people excited about the potential applications. Such proposals include (1) a well-defined computational problem, (2) a quantum algorithm to solve this problem, (3) a comparison best-case classical algorithm to solve the problem, and (4) a complexity-theoretic argument that, under a reasonable assumption, no classical algorithm can perform significantly better than current algorithms (so the quantum algorithm still provides a superpolynomial speedup). IBM says that Google “failed to fully account for plentiful disk storage” when estimating how long its traditional supercomputer would take to perform the calculation. A: Some people think it is hyping the state of the current technology too much and that it feeds unwarranted or unrealistic expectations of what the near-term implications are going to be.
