论文摘要
我们提出了以稳定量子状态稳定和操纵的驱动耗散主要平台。对于Majorana Box设置，在存在环境电磁噪声和隧道耦合到量子点的情况下，我们表明Majoraana扇区的时间演变受广泛参数状态的Lindblad Master方程的控制。对于单箱情况，可以通过调整合适的门电压来稳定任意纯状态（“暗状态”）。对于带有两个隧道耦合盒的设备，我们概述了如何设计黑暗的黑暗空间，即变性的黑暗状态，以及如何稳定容忍断层的铃铛状态。拟议的基于Majorana的黑暗空间平台依赖于拓扑保护机制的建设性相互作用以及工程驱动的耗散系统的自主量子误差校正功能。一旦有效的Majorana平台可用，只需要标准硬件要求就可以实现我们的想法。
We propose driven dissipative Majorana platforms for the stabilization and manipulation of robust quantum states. For Majorana box setups, in the presence of environmental electromagnetic noise and with tunnel couplings to quantum dots, we show that the time evolution of the Majorana sector is governed by a Lindblad master equation over a wide parameter regime. For the single-box case, arbitrary pure states (`dark states') can be stabilized by adjusting suitable gate voltages. For devices with two tunnel-coupled boxes, we outline how to engineer dark spaces, i.e., manifolds of degenerate dark states, and how to stabilize fault-tolerant Bell states. The proposed Majorana-based dark space platforms rely on the constructive interplay of topological protection mechanisms and the autonomous quantum error correction capabilities of engineered driven dissipative systems. Once a working Majorana platform becomes available, only standard hardware requirements are needed to implement our ideas.
