Feedback control on geometric phase in dissipative two-level systems
H. Y. Sun, P. L. Shu, C. Li +1
The effect of feedback on a two-level dissipative system is studied in this paper. The results show that it is possible to control the phase in the open system even if its state ca…
Measurable Concurrence of Mixed States
Chang-shui Yu, C. Li, He-shan Song
We show that bipartite concurrence for rank-2 mixed states of qubits is written by an observable which can be exactly and directly measurable in experiment by local projective meas…
On the effectiveness of the protocol creating the maximum entanglement of two charge-phase qubits by cavity field
C. Li, Y. B. Gao
We revisit the protocols to create maximally entangled states between two Josephson junction (JJ) charge phase qubits coupled to a microwave field in a cavity as a quantum data bus…
Enhanced the thermal Entanglement in Anisotropy XYZ Heisenberg Chain
L. Zhou, H. S. Song, Y. Q. Guo
The thermal entanglement in Heisenberg chain is investigated in the presence of external magnetic field . In the two-qubit system, the critical magnetic field is inc…
The dissipative dynamics of the field of two-photon Jaynes-Cummings model with Stark shift in dispersive approximation
L. Zhou, H. S. Song, Y. X. Luo
We present the dissipative dynamics of the field of two-photon Jaynes-Cummings model (JCM) with Stark shift in dispersive approximation and investigate the influence of dissipation…
