Building a quantum computer is one of the great scientific and engineering challenges of our time. A quantum processor stores and manipulates an amount of information that is exponential in the number of elementary bits, in contrast to classical information processing which is linear in the bit number. A quantum computer represents the most general type of information processor allowed by the known laws of physics, and it has been proven that a quantum computer can solve certain problems that are classically intractable. Efforts to build quantum processors are bolstered by the theoretical results of quantum fault tolerance, which prove that, in principle, decoherence of quantum states is not a fundamental obstacle to quantum computing as long as the error rate is below a threshold.

构建量子计算机是我们这个时代的巨大科学和工程挑战之一。量子处理器存储并操纵基本位数量指数的信息数量，与位数中线性的经典信息处理相反。量子计算机代表已知物理定律允许的最通用的信息处理器类型，并且已经证明量子计算机可以解决某些经典的问题。量子容错的理论结果支持构建量子处理器的努力，这些结果原则上证明，只要误差率低于阈值，量子状态的反熔就不是量子计算的基本障碍。
