The effect of permanent dipole moment on the polar molecule cavity quantum electrodynamics
Jing-Yun Zhao, Li-Guo Qin, Xun-Ming Cai +2
A dressed-state perturbation theory beyond the rotating waveapproxi-mation (RWA) is presented to investigate the interaction between a two level electronic transition of the polar…
The sudden birth and sudden death of thermal fidelity in a two-qubit XY model
Li-Jun Tian, Li-Guo Qin, Ying Jiang +1
We study the energy level crossings of the states and thermal fidelity for a two-qubit system in the presence of a transverse and inhomogeneous magnetic field. It is shown clearly…
The applications of the general and reduced Yangian algebras
Li-Guo Qin, Li-Jun Tian, Yan-Ling Jin +1
The applications of the general and reduced Yangian Y(sl(2)) and Y(su(3)) algebras are discussed. By taking a special constraint, the representation of Y(sl(2)) and Y(su(3)) can be…
An electro-optic waveform interconnect based on quantum interference
Li-Guo Qin, Zhong-Yang Wang, Shang-Qing Gong
The ability to modulate an optical field via an electric field is regarded as a key function of electro-optic interconnects, which are used in optical communications and informatio…
Entanglement of Two-Superconducting-Qubit System Coupled with a Fixed Capacitor
Li-Jun Tian, Li-Guo Qin, Hong-Biao Zhang
We study thermal entanglement in a two-superconducting-qubit system in two cases, either identical or distinct. By calculating the concurrence of system, we find that the entangled…
Quantum memories with electrically controlled storage and retrieval in an opto- and electro-mechanical cavity
Li-Guo Qin, Zhong-Yang Wang, Gong-Wei Lin +2
We propose a novel scheme to realize electrically controlled quantum memories in the opto- and electro-mechanical (OEM) cavity. Combining this OEM cavity with the mechanism of Elec…
