论文摘要
读取Majorana约束国家的均等自由度是展示其非亚伯交换特性的关键。在这里，我们提出了一个低能模型，描述了两臂设备中的局部边缘状态。我们研究了基于将超导体结合状态耦合到传感器读取电荷的量子点的均衡转换。系统的动力学，包括读取设备，使用量子跳跃方法全面分析。我们展示了产生的信号和噪声比如何区分本地Majoraana和Andreev结合状态。
Reading out the parity degree of freedom of Majorana bound states is key to demonstrating their nonabelian exchange properties. Here, we present a low-energy model describing localized edge states in a two-arm device. We study parity-to-charge conversion based on coupling the superconductor bound states to a quantum dot whose charge is read out by a sensor. The dynamics of the system, including the readout device, is analyzed in full using a quantum-jump approach. We show how the resulting signal and noise ratio differentiates between local Majorana and Andreev bound states.
