Stability of Pairwise Entanglement in a Decoherent Environment
Jian-Ming Cai, Zheng-Wei Zhou, Guang-Can Guo
Consider the dynamics of a two-qubit entangled system in the decoherence environment, we investigate the stability of pairwise entanglement under decoherence. We find that for diff…
Entanglement measurement based on two-particle interference
Jian-Ming Cai, Zheng-Wei Zhou, Guang-Can Guo
We propose a simple and realizable method using a two-particle interferometer for the experimental measurement of pairwise entanglement, assuming some prior knowledge about the qua…
Concatenating dynamical decoupling with decoherence-free subspaces for quantum computation
Yong Zhang, Zheng-Wei Zhou, Bo Yu +1
A scheme to implement a quantum computer subjected to decoherence and governed by an untunable qubit-qubit interaction is presented. By concatenating dynamical decoupling through b…
A general framework of nondistortion quantum interrogation
Zheng-Wei Zhou, Xingxiang Zhou, Xiu-Ding Lin +2
We present a general framework to study nondistortion quantum interrogation which preserves the internal state of the quantum object being detected. We obtain the necessary and suf…
High efficiency Nondistortion Quantum Interrogation of atoms in quantum superpositions
Xingxiang Zhou, Zheng-Wei Zhou, Guang-Can Guo +1
We consider the nondistortion quantum interrogation (NQI) of an atom prepared in a quantum superposition. By manipulating the polarization of the probe photon and making connection…
