Dynamical signature of edge state in the 1D Aubry-André model
H. Z. Shen, X. X. Yi, C. H. Oh
Topological feature has become an intensively studied subject in many fields of physics. As a witness of topological phase, the edge states are topologically protected and may be h…
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…
Extended Techniques for Feedback Control of A Single Qubit
Y. Yang, X. Y. Zhang, J. Ma +1
The protection of quantum states is challenging for non-orthogonal states especially in the presence of noises. The recent research breakthrough shows that this difficulty can be o…
Atom-molecule conversion system subject to phase noises
H. Z. Shen, Xiao-Ming Xiu, X. X. Yi
The dynamics of atom-molecule conversion system subject to dephasing noises is studied in this paper. With the dephasing master equation and the mean-field theory, we drive a Bloch…
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…
Optimal Lyapunov quantum control on two-level systems: convergence and extended techniques
L. C. Wang, S. C. Hou, X. X. Yi +2
Taking a two-level system as an example, we show that a strong control field may enhance the efficiency of optimal Lyapunov quantum control in [Hou et al., Phys. Rev. A \textbf{86}…
