Two-qubit gates within a decoherence-free subspace that is immune to aĬollective dephasing noise. Furthermore, we show its application for implementing single- and download: verb to transfer (data, files, etc.) from one location (such as a large computer or the cloud) to another (such as a smaller computer, smartphone, or storage device). Gate can approach unity as the single-atom cooperativity becomes sufficiently In principle, the success probability of the Postselected state, which simultaneously removes various detrimental effects ofĭissipation on the gate fidelity.

Success of our protocol is conditioned on projecting an auxiliary atom onto a Change the default download folder on your PC. Gate can be achieved without real excitations of cavity modes nor atoms.
