SCHEME FOR CONCENTRATION OF UNKNOWN ENTANGLED ATOMIC STATES
Yan-Lin Liao, Yan Zhao · Modern Physics Letters B · 2008
We proposed a physical scheme to concentrate unknown non-maximally entangled atomic states via cavity quantum electrodynamics (QED) techniques. In this scheme, the unique advantage is that the effects of the cavity decay and thermal field have been eliminated by using a classical driving field. The discussion indicates that it can be realized by current technologies.
