A mind-blowing glimpse into the near future, where quantum computing will have world-transforming effects.

The quantum computer is no longer the stuff of science fiction. Pioneering physicists are on the brink of unlocking a new quantum universe which provides a better representation of reality than our everyday experiences and common sense ever could. The birth of quantum computers - which, like Schrödinger's famous "dead and alive" cat, rely on entities like electrons, photons, or atoms existing in two states at the same time - is set to turn the computing world on its head.

In his fascinating study of this cutting-edge technology, John Gribbin updates his previous views on the nature of quantum reality, arguing for a universe of many parallel worlds where "everything is real." Looking back to Alan Turing's work on the Enigma machine and the first electronic computer, Gribbin explains how quantum theory developed to make quantum computers work in practice as well as in principle. He takes us beyond the arena of theoretical physics to explore their practical applications - from machines which learn through "intuition" and trial and error to unhackable laptops and smartphones. And he investigates the potential for this extraordinary science to create a world where communication occurs faster than light and teleportation is possible.

This is an exciting insider's look at the new frontier of computer science and its revolutionary implications.

在不久的将来，量子计算将产生改变世界的影响，这是令人震惊的一瞥。

量子计算机不再是科幻小说中的东西。开拓性的物理学家正处于开启一个新的量子宇宙的边缘，它提供了一个比我们的日常经验和常识更好的现实代表。量子计算机的诞生--与薛定谔著名的 "死而复生 "的猫一样，依赖于电子、光子或原子等实体同时存在于两种状态--将颠覆计算世界。

在他对这一尖端技术的迷人研究中，约翰-格里宾更新了他以前对量子现实的性质的看法，主张建立一个由许多平行世界组成的宇宙，在那里 "一切都很真实"。回顾阿兰-图灵在英格玛机和第一台电子计算机上的工作，格里宾解释了量子理论是如何发展到使量子计算机在实践中以及在原则上发挥作用的。他带领我们超越了理论物理学的领域，探索它们的实际应用--从通过 "直觉 "和试错学习的机器到无法破解的笔记本电脑和智能手机。他还研究了这一非凡科学的潜力，以创造一个通信速度超过光速和远程传输成为可能的世界。

这是一个令人兴奋的内部人士对计算机科学的新领域及其革命性影响的看法。
