Room-temperature steady-state entanglement in a four-mode optomechanical system
Tao Wang, Rui Zhang, Xue-mei Su
Stationary entanglement in a four-mode optomechanical system, especially under roomtemperature, is discussed. In this scheme, when the coupling strengths between the two target mod…

Super quantum discord for X-type states
Tao Li, Teng Ma, Yaokun Wang +2
Weak measurement is a new way to manipulate and control quantum systems. Different from projection measurement, weak measurement only makes a small change in status. Applying weak…

Non-commutativity and Local Indistinguishability of Quantum States
Teng Ma, Ming-Jing Zhao, Yao-Kun Wang +1
We study the local indistinguishability problem of quantum states. By introducing an easily calculated quantity, non-commutativity, we present an criterion which is both necessary…
