论文摘要
纯量子状态可以在受外部驱动力和环境模式耗散的开放量子系统中稳定。我们表明，驱动的耗散性（DD）Majorana设备为稳定退化状态歧管（“黑暗空间”）和在黑暗空间中操纵状态（非天然（非DD）Majorana设备和DD平台都具有拓扑性琐碎的构件，都提供了关键优势。对于两个隧道耦合的Majorana盒子，否则仅使用标准硬件元素（例如，带有驱动隧道链路的嘈杂的电磁环境和量子点），我们提出了深色Qubit编码。我们预计，由于基于DD的自主误差校正和拓扑的阴谋，我们的容错水平异常高。
Pure quantum states can be stabilized in open quantum systems subject to external driving forces and dissipation by environmental modes. We show that driven dissipative (DD) Majorana devices offer key advantages for stabilizing degenerate state manifolds (`dark spaces') and for manipulating states in dark spaces, both with respect to native (non-DD) Majorana devices and to DD platforms with topologically trivial building blocks. For two tunnel-coupled Majorana boxes, using otherwise only standard hardware elements (e.g., a noisy electromagnetic environment and quantum dots with driven tunnel links), we propose a dark qubit encoding. We anticipate exceptionally high fault tolerance levels due to a conspiracy of DD-based autonomous error correction and topology.
