摘要

提出了一种采用反馈和弱测量的量子误差校正方案。这提供了一种不使用量子纠错标准工具(投影测量和快速控制的统一门)来保护未知量子态免受错误影响的方法，并且由于所需的侧处理很少，因此可以实际实现。我们通过模拟一个防止位翻转的简单场景来评估我们的方案的性能。

Quantum control and quantum error correction

We describe a scheme for quantum error correction that employs feedback and weak measurement. This provides a method of protecting an unknown quantum state against errors that does not use the standard tools of quantum error correction - projective measurements and fast controlled unitary gates - and is practicably implementable because of the little side processing required. We evaluate the performance of our scheme by simulating a simple scenario of protection against bit-flips.
