Google is developing quantum computing
Moore's Law means that the chip computing power of traditional computers doubles every 18 months. That is, growth is a power of 2, and this doubling is of course exponential. Hartmut Neven, director of the Google Quantum Artificial Intelligence Laboratory, first proposed at the Google Quantum Spring Symposium in May 2019 that the chip computing power of quantum computers was a double exponential growth, which was a power-up of 2 power. The process of quantum computer surpassing computer with double exponential growth is the result of the combination of two exponential factors. Specifically, quantum computers have inherent index advantages over classical computers. If a quantum circuit has 4 qubits, then a 16-bit classical circuit can be equivalent to its computational power; while the second exponential factor is derived from the rapid evolution of quantum processors. The realization of quantum hegemony is that the quantum computer is fully rolled and supercomputerized, with 3 minutes and 20 seconds to 10,000 years. The former's computing power and performance are 175 million times that of the latter. Moreover, quantum computing combines the two biggest technological changes in the past half century, one is information technology, and the other is quantum mechanics. By replacing the traditional computer binary logic with the rules of quantum mechanics, you can overcome many difficult computing tasks.
Don't make up the short board, but find the longest longboard and make it infinite. No one will compete with you, you will win. Has Google caught the longest board again, and will it be infinitely long with Google’s strength? Google recently published a paper on quantum technology. Although the paper was published on the National Aeronautics and Space Administration (NASA) official website and subsequently deleted, it has caused sensation and concern around the world. It is also said that the reason for the withdrawal was that the study had not been peer-reviewed, so the paper was withdrawn from NASA. By convention, academic results should be published in academic journals before they can be used for news and mass communication. The premise of publication in academic journals is subject to review by peer experts, and the review process usually takes weeks or months. But it still aroused the expectation and attention of the whole world.
Because this piece of the longest board, now known to be able to complete quantum computing, has caused infinite imagination. Once the application is realized, a dedicated quantum computing system capable of coherent manipulation of hundreds of qubits can be realized, which is applied to combinatorial optimization, quantum chemistry, machine learning, etc. with practical value, and guides new material design and drug development. In addition, entering the general programmable quantum computer stage, it can coherently manipulate hundreds of millions of qubits to realize a fault-tolerant quantum computer, which can play a subversive role in blockchain, classic password cracking, big data search, artificial intelligence and so on.
谷歌正在研发量子计算
摩尔定律是指,传统计算机的芯片算力每18个月性能翻倍。即增长是按2的幂增长,这种翻番当然也是指数级的。谷歌量子人工智能实验室主任Hartmut Neven在2019年5月的谷歌量子春季研讨会上第一次提出量子计算机的芯片算力是双指数快速增长,是按2的幂的幂增长。量子计算机以双指数增长超越计算机的过程是两个指数因子相互组合的结果,具体为,量子计算机比经典计算机具有先天的指数优势。如果一个量子电路有4个量子比特,那么一个16比特的经典电路才能与其计算能力等效;同时第二个指数因子源于量子处理器的快速演进。量子霸权的实现就是量子计算机全面碾压超算,以3分20秒比1万年,前者的计算能力和性能是后者的1.75亿倍。而且,量子计算是结合了过去半个世纪以来两个最大的技术变革,一是信息技术,二是量子力学。使用量子力学的规则替换传统计算机二进制逻辑来计算,就可以攻克许多难以完成的计算任务。
不要补短板,而要找到最长的长板,把它变得无限长,没有人跟你竞争,你就赢了。谷歌是否又一次 抓到了那块最长的板,将来凭借谷歌的实力把它变得无限长?谷歌最近发表一篇量子这方面的论文,虽然论文刊发在美国国家航空航天局(NASA)官网上随后又被删除,但是已经引起了全世界的轰动和关注。另外据说,被撤的原因是这项研究还没有经过同行评审,所以论文从NASA被撤下来了,按惯例,学术成果应首先在学术期刊发表,才能用于新闻和大众传播。在学术期刊发表的前提又是需经同行专家评审,而且评审过程一般需要数周或者数月时间。但是还是引起了全世界的期待和关注。
因为这块现在已知能够完成量子计算的最长的板,引起了人们无限的遐想。一旦实现应用,可以实现数百个量子比特相干操纵的专用型量子计算系统,应用于具有实用价值的组合优化、量子化学、机器学习等方面,指导新材料设计、药物研发等。另外,进入到通用可编程的量子计算机阶段,能够相干操纵数亿量子比特,实现可容错的量子计算机,能在区块链、经典密码破解、大数据搜索、人工智能等方面发挥颠覆性作用。
