CNOT gate by adiabatic passage with an optical cavity
Résumé
We propose a. scheme for the construction of a CNOT gate by adiabatic passage in an optical cavity. In opposition to a previously proposed method, the technique is not based on fractional adiabatic passage, which requires the control of the ratio of two pulse amplitudes. Moreover, the technique constitutes a decoherence-free method in the sense that spontaneous emission and cavity clamping are avoided since the dynamics follows dark states.
