Geometric measure of quantum discord and the geometry of a class of two-qubit states
Wei Song, Long-Bao Yu, Ping Dong +3
We investigate the geometric picture of the level surfaces of quantum entanglement and geometric measure of quantum discord (GMQD) of a class of X-states, respectively. This pictor…
Storage and retrieval of continuous-variable polarization-entangled cluster states in atomic ensembles
Da-Chuang Li, Chun-Hua Yuan, Zhuo-Liang Cao +1
We present a proposal for storing and retrieving a continuous-variable quadripartite polarization-entangled cluster state, using macroscopic atomic ensembles in a magnetic field. T…
Spin dynamics in triangular lattice antiferromagnets CuCrMgO
Renwen Li, Zhe Qu, Wei Tong +1
The electron spin resonance (ESR) spectroscopy was employed to investigate the spin dynamics in triangular lattice antiferromagnets CuCrMgO with 0 and 0.02.…
Dynamics of quantum discord in the purification process
Wei Song, Lin Chen, Ming Yang +1
We investigate the dynamics of quantum discord during the purification process. In the case of Werner states, it is shown that quantum discord is increased after a round of purific…
