Phase-dependent double optomechanically induced transparency in a hybrid optomechanical cavity system with coherently mechanical driving
Shi-Chao Wu, Li-Guo Qin, Jian Lu +1
We propose a scheme that can generate a tunable double optomechanically induced transparency (OMIT) in a hybrid optomechanical cavity system, in which the mechanical resonator of a…
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…
Decoherence from a spin-chain with three-site interaction
Li-Jun Tian, Cai-Yun Zhang, Li-Guo Qin
We investigate the time evolution of quantum discord and entanglement for two-qubit coupled to a spin chain with three-site interaction in the weak-coupling region. If the quantum…
Quantum entanglement and teleportation in quantum dot
Li-Guo Qin, Li-Jun Tian, Guo-Hong Yang
We study the thermal entanglement and quantum teleportation using quantum dot as a resource. We first consider entanglement of the resource, and then focus on the effects of differ…
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…
Fidelity susceptibility and geometric phase in critical phenomenon
Li-Jun Tian, Chang-Qing Zhu, Hong-Biao Zhang +1
Motivated by recent development in quantum fidelity and fidelity susceptibility, we study relations among Lie algebra, fidelity susceptibility and quantum phase transition for a tw…
