Decay and storage of multiparticle entangled states of atoms in collective thermostat
arXiv:quant-ph/0611117 · doi:10.1103/PhysRevA.74.042313
Abstract
We derive a master equation describing the collective decay of two-level atoms inside a single mode cavity in the dispersive limit. By considering atomic decay in the collective thermostat, we found a decoherence-free subspace of the multiparticle entangled states of the W-like class. We present a scheme for writing and storing these states in collective thermostat.
