Dissipative preparation of entanglement in optical cavities
Dissipative preparation entanglement optical cavities
2010/11/8
We propose a novel scheme for the preparation of a maximally entangled state of two atoms in an optical cavity. Starting from an arbitrary initial state, a singlet state is prepared as the unique fixe...
