论文摘要
由于需要对Majorana Qubits和表面代码稳定器进行量子测量的动机，我们分析了在环境噪声影响下的双点干涉仪的性能。双点设置设计允许在主方程方法中通过Majoraana岛的点之间的整个多个隧道过程进行核算。在导致点之间介导的有效耦合的共同隧道状态中，主方程方法使我们能够为测量电流获得分析解决方案。测量质量以优异数字为特征，例如测量信号的可见性，是针对异常的反矫正效应而不是“ dath'dephasing进行的。预计这项工作中获得的结果将对未来的Majorana量子和稳定器测量的实验有用。
Motivated by the need of quantum measurement of Majorana qubits and surface-code stabilizers, we analyze the performance of a double-dot interferometer under the influence of environment noise. The double-dot setup design allows accounting for the full multiple tunneling process between the dots through the Majorana island, within a master equation approach. In the co-tunneling regime, which results in a Majorana-mediated effective coupling between the dots, the master equation approach allows us to obtain analytic solutions for the measurement currents. The measurement quality, characterized by figures of merit such as the visibility of measurement signals, is carried out in regard to the unusual decoherence effect rather than `which-path' dephasing. The results obtained in this work are expected to be useful for future experiments of Majorana qubit and stabilizer measurements.
