Engineering Multi-atom Entangled States via Cavity Decay
Zheng Shi-Biao · Communications in Theoretical Physics · 2007
A scheme is proposed for the generation of entangled states for multiple atoms trapped in a cavity by detecting photon decay. The scheme is valid no matter when the effective atom-cavity coupling strength is larger than the cavity decay rate or not, which is of importance in view of experiment. The fidelity of entanglement is insensitive to the inefficiency of the photo-detector. The scheme does not require a photon to be initially injected into the cavity.
