Effective generation of Ising interaction and cluster states in coupled microcavities
Pengbo Li, Qihuang Gong, Guangcan Guo
We propose a scheme for realizing the Ising spin-spin interaction and atomic cluster states utilizing trapped atoms in coupled microcavities. It is shown that the atoms can interac…
Deterministic generation of polarization-entangled photon pairs in a cavity-QED system
Pengbo li, Ying Gu, Qihuang Gong +1
We propose a cavity-QED scheme that can deterministically generate Einstein-Podosky-Rosen polarization-entangled photon pairs. A four-level tripod atom successively couples to two…
Generation of two-mode field squeezing through selective dynamics in cavity QED
Pengbo Li
We propose a scheme for the generation of a two-mode field squeezed state in cavity QED. It is based on two-channel Raman excitations of a beam of three-level atoms with random arr…
Entanglement Entropy: Helicity versus Spin
Song He, Shuxin Shao, Hongbao Zhang
For a massive spin 1/2 field, we present the reduced spin and helicity density matrix, respectively, for the same pure one particle state. Their relation has also been developed. F…
Quantum Helicity Entropy of Moving Bodies
Song He, Shuxin Shao, Hongbao Zhang
Lorentz transformation of the reduced helicity density matrix for a massive spin 1/2 particle is investigated in the framework of relativistic quantum information theory for the fi…
