Discrimination of Coherent States via Atom-Field Interaction without Rotation Wave Approximation
Jin-Hua Zhang, Fu-Lin Zhang, Mai-Lin Liang +2
The quantum state discrimination is an important part of quantum information processing. We investigate the discrimination of coherent states through Jaynes-Cummings (JC) model int…
Sequential state discrimination with quantum correlation
Jin-Hua Zhang, Fu-Lin Zhang, Mai-Lin Liang
The sequential unambiguous state discrimination (SSD) of two states prepared in arbitrary prior probabilities is studied, and compared with three strategies that allow classical co…
Assisted optimal state discrimination without entanglement
Li-Fang Xu, Fu-Lin Zhang, Mai-Lin Liang +1
A fundamental problem in quantum information is to explore the roles of different quantum correlations in a quantum information procedure. Recent work [Phys. Rev. Lett., 107 (2011)…
Phase-Entanglement Complementarity with Time-Energy Uncertainty
Fu-Lin Zhang, Mai-Lin Liang
We present a unified view of the Berry phase of a quantum system and its entanglement with surroundings. The former reflects the nonseparability between a system and a classical en…
Sequential State Discrimination and Requirement of Quantum Dissonance
Chao-Qian Pang, Fu-Lin Zhang, Li-Fang Xu +2
We study the procedure for sequential unambiguous state discrimination. A qubit is prepared in one of two possible states, and measured by two observers Bob and Charlie sequentiall…
Dirac equation with a magnetic field in 3D non-commutative phase space
Mai-Lin Liang, Ya-Bin Zhang, Rui-Lin Yang +1
For a spin-1/2 particle moving in a background magnetic field in noncommutative phase space, Dirac equation is solved when the particle is allowed to move off the plane that the ma…
Most robust and fragile two-qubit entangled states under depolarizing channels
Chao-Qian Pang, Fu-Lin Zhang, Yue Jiang +2
For a two-qubit system under local depolarizing channels, the most robust and most fragile states are derived for a given concurrence or negativity. For the one-sided channel, the…
Speed of disentanglement in multi-qubit systems under depolarizing channel
Fu-Lin Zhang, Yue Jiang, Mai-Lin Liang
We investigate the speed of disentanglement in the multiqubit systems under the local depolarizing channel, in which each qubit is independently coupled to the environment. We focu…
