Proposal for realization of a Toffoli gate via cavity-assisted collision
H. Ollivier, P. Milman
abstract: Cavity QED is a versatile tool to explore small scale quantum information
processing. Within this setting, we describe a particular protocol for
implementing a Toffoli gate with Rydberg atoms and a cavity field. Our scheme
uses both resonant and non resonant interactions, and in particular a cavity
assisted atomic collision. The experimental feasibility of the protocol is
carefully analyzed with the help of numerical simulations and takes into
account the decoherence process. Moreover, we show that our protocol is optimal
within the constraints imposed by the experimental setting.
