Abstract: | 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 damping are avoided since the dynamics follows dark
states. |
