Detecting EPR steering via two classes of local measurements
Le-Min Lai, Tao Li, Shao-Ming Fei and Zhi-Xi Wang
We study the Einstein-Podolsky-Rosen (EPR) steering and present steerability criteria for arbitrary qubit-qudit (qudit-qubit) systems based on mutually unbiased measurements (MUMs) and general symmetric informationally complete measurements (general SIC-POVMs). Avoiding the usual complicated steering inequalities, these criteria can be more operational than some existing criteria, and implemented experimentally. Detailed examples are given to illustrate the efficiency of the criteria in both computation and experimental implementation.
