对抗量子噪声

Against Quantum Noise

A. Ekert, C. Macchiavello

摘要:

这是对如何保护量子态免受由于与环境的不受控制的相互作用而引起的耗散和退相干的简要描述。我们讨论了基于“对称化”和“量子纠错“两种技术的量子态的重相干和稳定化。我们说明了我们的考虑与最流行的量子光学模型的系统与环境的相互作用,通常用于描述自发发射,并显示在这种情况下的量子纠错的好处。

英文摘要:

This is a brief description of how to protect quantum states from dissipation and decoherence that arise due to uncontrolled interactions with the environment. We discuss recoherence and stabilisation of quantum states based on two techniques known as "symmetrisation" and "quantum error correction". We illustrate our considerations with the most popular quantum-optical model of the system-environment interaction, commonly used to describe spontaneous emission, and show the benefits of quantum error correction in this case.
