自治子系统量子纠错的纳米光子电路设计
Design of nanophotonic circuits for autonomous subsystem quantum error correction
摘要:
我们重新应用我们的方法来设计纳米光子量子存储器,以制定一个光网络,自主保护一个单一的逻辑量子比特对任意单量子比特错误。该网络模拟9量子位Bacon-Shor子系统代码,通过连续的、与时间无关的光相互作用和单一处理的光场的相干反馈来取代传统的离散综合征测量和校正步骤。
英文摘要:
We reapply our approach to designing nanophotonic quantum memories to formulate an optical network that autonomously protects a single logical qubit against arbitrary single-qubit errors. Emulating the 9 qubit Bacon-Shor subsystem code, the network replaces the traditionally discrete syndrome measurement and correction steps by continuous, time-independent optical interactions and coherent feedback of unitarily processed optical fields.
