摘要: 基于光子与量子点自旋的相互作用设计了一个实现三量子比特重复量子纠错码的方案。在该方案中,偏振光束分光器,光子探测器和微柱腔是必须的,且能实现单电子自旋的非破坏性测量,对量子信息处理具有重要意义。对实验方案的可行性讨论表明:该方案在当前实验技术范围内是切实可行的。

关键词: 量子纠错码,光子-自旋相互作用,非破坏性测量

Abstract: A scheme for implementing a three-qubit repetition quantum error-correction code with photon-spin interactions is presented. Polarizing beam splitters, photon detectors and micropillar cavities are used to realize quantum nondemolition measurement of the single spin, which are very important in quantum information processing. It is shown that this scheme is feasible in the current experimental technology.

Key words: quantum error-correction code, photon-spin interaction, nondemolition measurement
