| Summary: | J. Phys. B: At. Mol. Opt. Phys. 46 104004 (2013); Special issue on
the 20th anniversary of quantum state engineering A scheme is presented for the dissipative preparation of generalised Bell
states of two-qubits, within the context of cavity QED. In the suggested
protocol the dissipative processes of spontaneous emission and cavity loss are
no longer undesirable, but essential to the required dynamics. Extremely long
lived target states are achieved, with fidelities of near unity, utilising
cooperativities corresponding to currently available optical cavities.
Furthermore, the suggested protocol exhibits excellent scaling of relevant
characteristics, with respect to cooperativity, such that improved results may
be obtained as the development of experimental capabilities continues. |
