Decoherence-free quantum memory for photonic state using atomic ensembles
Feng Mei, Ya-Fei Yu, Zhi-Ming Zhang
Large scale quantum information processing requires stable and long-lived quantum memories. Here, using atom-photon entanglement, we propose an experimentally feasible scheme to re…

Decoherence of two qubits in a non-Markovian squeezed reservoir
Fa-Qiang Wang, Zhi-Ming Zhang, Rui-Sheng Liang
The decoherence of two initially entangled qubits in a squeezed vacuum cavity has been investigated exactly. The results show that, first, in principle, the disentanglement time de…

An experiential formula for the energy eigenvalues of a particle in a one-dimension finite-deep square well potential
Zhi-Ming Zhang, Chun-Hua Yuan
We propose an experiential formula for the calculation of the energy eigenvalues of a particle moving in a one-dimension finite-deep square well potential after some physical consi…
