Uncertainty-induced quantum nonlocality
Shao-xiong Wu, Jun Zhang, Chang-shui Yu +1
Based on the skew information, we present a quantity, uncertainty-induced quantum nonlocality (UIN) to measure the quantum correlation. It can be considered as the updated version…
Quantum correlation measure in arbitrary bipartite systems
Chang-shui Yu, Shao-xiong Wu, Xiao-guang Wang +2
A definition of quantum correlation is presented for an arbitrary bipartite quantum state based on the skew information. This definition not only inherits the good properties of sk…
Bipartite concurrence and localized coherence
Chang-shui Yu, He-shan Song
Based on a proposed coherence measure, we show that the local coherence of a bipartite quantum pure state (coherence of its reduced density matrix) is exactly the same as the minim…
Entangling Power in the Deterministic Quantum Computation with One Qubit
Chang-shui Yu, X. X. Yi, He-shan Song +1
The deterministic quantum computing with one qubit (DQC1) is a mixed-state quantum computation algorithm that evaluates the normalized trace of a unitary matrix and is more powerfu…
The Dual Roles of Quantum Discord in a Non-demolition Probing Task
Chang-shui Yu, Jia-sen Jin, Heng Fan +1
We present a non-demolition quantum information processing task of probing the information of a class of quantum state. In this task, the information is extracted by some unitary e…
Driving three atoms into a singlet state in an optical cavity via adiabatic passage of a dark state
Mei Lu, Yan Xia, Jie Song +1
In this paper, we propose an efficient scheme to drive three atoms in an optical cavity into a singlet state via adiabatic passage. Appropriate Rabi frequencies of the classical fi…
