Abstract

We investigate the feasibility of implementing an elementary building block for quantum information processing. The combination of a deterministic single photon source based on vacuum stimulated adiabatic rapid passage [1,2], and a quantum memory based on electromagnetically induced transparency in atomic vapour is outlined [3]. Both systems are able to produce and process temporally shaped wavepackets which provides a way to maintain the indistinguishability of retrieved and original photons. We also propose an efficient and robust ‘repeat-until-success’ quantum computation scheme based on this hybrid architecture.
