Abstract
In this paper, we propose a scheme of remote quantum state preparation and transfer that use a double-sided cavity system, in which a singly charged quantum dot is embedded in a double-sided optical microcavity with partially reflective top and bottom mirrors. The implementation of the scheme mainly depends on the interaction between the input single-photon pulse and the spins of electrons in the coupling system. Discussions about the effect of the cavity loss, side leakage and exciton–cavity coupling strength for the fidelity of generated states show that the fidelity can remain high enough by controlling these parameters. Therefore, the current scheme is feasible in the experiment.
