1307.1761 (Zhen-ni Li et al.)

Probing quantum entanglement, quantum discord, classical correlation,
and the quantum state without disturbing them

Zhen-ni Li, Jia-sen Jin, Chang-shui Yu
In this paper, we present schemes for a type of one-parameter bipartite quantum states to probe the quantum entanglement, the quantum discord, the classical correlation and the quantum state based on the cavity QED. It is shown that our detection does not influence all these measured quantities. We also discuss how the spontaneous emission introduced by our probe atom influences our detection.
