Quantum-discord-induced superradiance and subradiance in a system of two separated atoms
Shi-Qing Tang, Ji-Bing Yuan, Xin-Wen Wang +1
We investigate collective radiant properties of two separated atoms in X-type quantum states. We show that quantum correlations measured by quantum discord (QD) can induce and enha…
Impurity-induced Dicke quantum phase transition in an impurity-doped cavity-Bose-Einstein condensate
Ji-Bing Yuan, Ya-Ju Song, Le-Man Kuang
We present a new generalized Dicke model, an impurity-doped Dicke model (IDDM), by the use of an impurity-doped cavity-Bose-Einstein condensate. It is shown that the impurity atom…
Nonmaximally entangled states can be better for quantum correlation distribution and storage
Xin-Wen Wang, Shi-Qing Tang, Ji-Bing Yuan +1
For carrying out many quantum information protocols entanglement must be established in advance between two distant parties. Practically, inevitable interaction of entangled subsys…
