两个量子比特可操纵性的必要条件,从本地操作的考虑

Necessary conditions for steerability of two qubits, from consideration of local operations

Travis J. Baker, Howard M. Wiseman

摘要:

EPR引导是指一个观察者通过进行本地测量来说服远处观察者他们共享纠缠的能力。确定哪些国家允许演示EPR转向仍然是一个悬而未决的问题。在这里,我们概述并演示了一种方法,分析构建新的类的两个量子比特的状态,这是不可操纵的任意投影测量,从考虑本地操作的督导方上已知的状态是不可操纵的。

英文摘要:

EPR-steering refers to the ability of one observer to convince a distant observer that they share entanglement by making local measurements. Determining which states allow a demonstration of EPR-steering remains an open problem in general. Here, we outline and demonstrate a method of analytically constructing new classes of two-qubit states which are non-steerable by arbitrary projective measurements, from consideration of local operations performed by the steering party on states known to be non-steerable.
