Experimental Detection of Quantum Entanglement

Ming Li, Ming-Jing Zhao, Shao-Ming Fei and Xianqing Li-Jost

Abstract

In this review, we introduce some methods for detecting or measuring entanglement. Several non-linear entanglement witnesses are presented. We derive a series of Bell inequalities whose maximally violations for any multipartite qubit states can be calculated by using our formulas. Both the non-linear entanglement witnesses and the Bell inequalities can be operated experimentally. Thus they supply an effective way for detecting entanglement. We also introduce some experimental methods to measure the entanglement of formation, and the lower bound of the convex-roof extension of negativity.
