What the Hell Is a Quantum Computer and How Excited Should I Be? Some scientists have suggested the human brain can in fact be a quantum computer . That is why we need quantum computers . Why is a quantum computer hard to build? 据报道,谷歌在2017年首次组装了一台量子计算机 ,但这一尝试失败了,因为72个超导量子位系统太难控制。 Google first assembled a quantum computer back in 2017, but the first attempt was unsuccessful, as the machine was difficult to control.

在许多方面,建造一台量子计算机 的努力,是关于我们对周围世界还不了解的所有事情的一堂大课。 In many ways, the exercise of building a quantum computer is one long lesson in everything we don't yet understand about the world around us. 你曾经想要摆弄一台量子计算机 ,但却发觉没有能够让你进入实验室的关系吗? Have you ever want to fiddle with a quantum computer , but they found no able to let you into the lab relationships do? 通过使用这种算法,一台量子计算机 破解密码可以比任何普通(典型)计算机都要快。 By using this algorithm, a quantum computer would be able to crack codes much more quickly than any ordinary(or classical) computer could. 在1990年代中期,人们发现,如果您拥有一台量子计算机 ,便能够解决一些非常困难的问题。 Around the mid-1990s it was discovered that if you had a quantum computer , you would be able to solve some really hard problems. 一台量子计算机 将很有可能由百来个或数千个量子位组成。A quantum computer would most likely consist of hundred or thousands of qubits. 然而,一台量子计算机 将能够在几天之内打破这种密码屏蔽。 However, a quantum computer would be able to break this kind of cryptographic shield in a matter of days. 年,研究人员估计,一台量子计算机 需要10亿个量子位元才能可靠地完成这项工作。 In 2015, researchers estimated that a quantum computer would need a billion qubits to do the job reliably. 无论如何,就现状而言,几乎每一台量子计算机 都是花费上百万美元,几乎疯狂的科学家们通力合作的大项目。 All the same, as of right now, nearly every quantum computer is a multi-million dollar borderline mad-scientist project that looks the part. MITTR:您有一台量子计算机 来执行非常狭窄的特定任务。 MIT TR: You got a quantum computer to perform a very narrow, specific task. 还有另一台量子计算机 可以跟踪我们所处的量子计算研究的狂野西部时代。 There's another quantum computer to keep track of in this Wild West era of quantum computing research we're in. A quantum computer would be able to break a lot of the security protocols that exist today. 一台量子计算机 将可以破解世上所有的加密方式,而量子加密也将真正无懈可击。A quantum computer will be able to crack all the encryption methods in the world, and quantum encryption will be truly impeccable. 有一天,一台量子计算机 可能会很容易地执行这个因式分解,并使这个加密方法变得无用。 One day, a quantum computer might easily perform this factoring and render this cryptographic method useless. 在许多方面,建造一台量子计算机 的努力,是关于我们对周围世界还不了解的所有事情的一堂大课。 In many ways, the effort to build a quantum computer is a big lesson about everything we don't know about the world around us. 如果一台量子计算机 可以解决经典计算机无法解决的问题,那并不必然意味着解决方案将难以检验。 If a quantum computer can solve a problem that a classical computer cannot, that doesn't automatically mean the solution will be hard to check. So if we want to simulate it, we need a quantum computer .”. 但是从理论上讲,一台量子计算机 在几个小时内就能解决这一问题。 Theoretically, a quantum computer could solve these problems in a matter of minutes. 但是从理论上讲,一台量子计算机 在几个小时内就能解决这一问题。 While a quantum computer can solve this problem within an hour.但是从理论上讲,一台量子计算机 在几个小时内就能解决这一问题。 Theoretically, a quantum computer could solve the problem in hours. 例如,一台量子计算机 可以很容易地破解保护网上银行安全的代码。 For example, one quantum computer could easily crack the codes that keep internet banking secure. 一台量子计算机 ,它能以某种方式用不可思议的速度做哈希运算。A quantum computer , that is somehow able to hash at unbelievable speed.他们所致力解决的问题在某种程度上很可笑:开发一台量子计算机 。 The problem they settled on is in a way laughably contrived: Being a quantum computer . 比特币使用的椭圆曲线签名方案早在2027年就可以被一台量子计算机 彻底打破,”Aggarwal和他的同事写道。 The elliptic curve signature scheme used by Bitcoin… could be completely broken by a quantum computer as early as 2027,” Aggarwal and his colleagues wrote. How to build a quantum computer .
