Decoherences-protected implementation of quantum gates
Chunfeng Wu, Chunfang Sun, Jing-Ling Chen +1
We present a scheme to implement a universal set of quantum gates based on achievable interactions, and the gates can be protected against decoherences through dynamical-decoupling…
Non-adiabatic holonomic quantum computation in linear system-bath coupling
Chunfang Sun, Gangcheng Wang, Chunfeng Wu +4
Non-adiabatic holonomic quantum computation in decoherence-free subspaces protects quantum information from control imprecisions and decoherence. For the non-collective decoherence…
Quantum nonlocality of massive qubits in a moving frame
Hong-Yi Su, Yu-Chun Wu, Jing-Ling Chen +2
We perform numerical tests on quantum nonlocality of two-level quantum systems (qubits) observed by a uniformly moving observer. Under a suitable momentum setting, the quantum nonl…
Quantumness of Product States
Jing-Ling Chen, Hong-Yi Su, Chunfeng Wu +1
Product states do not violate Bell inequalities. In this work, we investigate the quantumness of product states by violating a certain classical algebraic models. Thus even for pro…
Einstein-Podolsky-Rosen Steering in Quantum Phase Transition
Chunfeng Wu, Jing-Ling Chen, Dong-Ling Deng +3
We investigate the Einstein-Podolsky-Rosen (EPR) steering and its criticality in quantum phase transition. It is found that the EPR steerability function of the ground state of XY…
Einstein-Podolsky-Rosen Steerability Criterion for Two-Qubit Density Matrices
Jing-Ling Chen, Hong-Yi Su, Xiang-Jun Ye +2
We propose a sufficient criterion to detect Einstein-Podolsky-Rosen steering for arbitrary two-qubit density matrix . Here are respect…
