论文摘要
测量Majorana熵$ s_m = k_b \ log（2^\ frac {1} {2}）$可能会独特地揭示纳米级设备的初始平衡状态是否具有主要均衡状态，并且随后的操作与本质上非宽大型非局部对非亚洲主要界限的状态和与Trif trif nontriv nontrif nort-trivial-trivian Ianselian Ianselian Iansal-Abel-aberian Iantal Iantal Iantal Iantal Iantal Iantal Iance Interal Interal Inctal Intally Bains with。但是，在现实的设置中，两种主要模式都不可避免地参与了隧道过程。我们表明，即使一个Majorana模式的隧道幅度被大大抑制，Majorana熵废墟和直接实验也将在一般检测到熵$ s \ ll s_m $中。为了避免这个普遍的问题，我们通过Majorana模式的隧道阶段提出了Majorana熵复兴的机制，并证明，要成功地观察通用Majoragan Platau $ S = S_M $，一个人应该明智地调整隧道阶段，而不是使它们无法控制。适当的Majorana熵测量值的实际可行性由现代实验室中可以实现的参数提供的示例支持。
Measuring the Majorana entropy $S_M=k_B\log(2^\frac{1}{2})$ may uniquely reveal whether an initial equilibrium state of a nanoscale device is of Majorana nature and subsequent operations deal with an essentially nonlocal pair of non-Abelian Majorana bound states and not with trivial or other accidental non-Abelian states. However, in realistic setups both Majorana modes are inevitably involved in tunneling processes. We show that even when the tunneling amplitude of one Majorana mode is significantly suppressed, the Majorana entropy ruins and straightforward experiments will in general detect entropy $S\ll S_M$. To avoid this general problem we present a mechanism of the Majorana entropy revival via the tunneling phases of the Majorana modes and demonstrate that to successfully observe the universal Majorana plateau $S=S_M$ one should intelligently tune the tunneling phases instead of leaving them uncontrolled. Practical feasibility of appropriate Majorana entropy measurements is supported by an example with parameters well achievable in modern labs.
