任何量子系统都不可避免地与环境相互作用,从而导致退相干。虽然环境通常是不可接近的,但我们能否保护我们的系统免受噪声的影响,以保持其量子相干性?量子信息科学中开发的一种技术,称为量子纠错码,可以完成这项工作。其主要思想是将系统“编码”到整个N-量子比特空间的子空间中,称为“代码空间”,这样由系统的退相干引起的错误可以被“纠正”。
Any quantum system inevitably interacts with the environment which causes decoherence. While the environment is generally inaccessible, can we protect our system against noise to maintain its quantum coherence? One technique developed in quantum information science, called the quantum error-correcting codes, does the job. The main idea is to “encode” the system into a subspace of the entireN-qubit space, called the “code space”, such that the errors caused by decoherence of the system can be “corrected”.
