Preparation of Genuinely Entangled Six-Atom State via Cavity Quantum Electrodynamics
Wen Zhang, Yimin Liu, Xiaofeng Yin, Zhanjun Zhang · Communications in Theoretical Physics · 2011
A cavity quantum electrodynamics scheme for preparing a genuinely entangled state [A. Borras, et al., J. Phys. A 40 (2007) 13407 ] on six two-level atoms is proposed. In the scheme, the atom-cavity detuning is much bigger than the atom-cavity coupling strength and the necessary preparation time is much shorter than the Rydberg-atom lifespan. Hence the scheme has two distinct features, i.e., insensitive to the cavity decay and the atom radiation.
