Generation of entangled states for many multilevel atoms in a thermal cavity and ions in thermal motion
arXiv:1202.5384 · doi:10.1103/PhysRevA.68.035801
Abstract
We propose a scheme for generating entangled states for two or more multi-level atoms in a thermal cavity. The photon-number dependent parts in the effective Hamiltonian are canceled with the assistant of a strong classical field. Thus the scheme is insensitive to both the cavity decay and the thermal field. The scheme does not require individual addressing of the atoms in the cavity. The scheme can also be used to generate entangled states for many hot multi-level ions.
