This chapter introduces cavity-based light-matter quantum interfaces, with a single atom or ion in strong coupling to a high-finesse optical cavity. We discuss the deterministic generation of indistinguishable single photons from these systems; the atom-photon entanglement intractably linked to this process; and the information encoding using spatio-temporal modes within these photons. Furthermore, we show how to establish a time-reversal of the aforementioned emission process to use a coupled atom-cavity system as a quantum memory. Along the line, we also discuss the performance and characterisation of cavity photons in elementary linear-optics arrangements with single beam splitters for quantum-homodyne measurements.

Quantum memories for single photons from cavity-QED

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 indistinguish ability of retrieved and original photons. We also propose an efficient and robust repeat-until-success quantum computation scheme based on this hybrid architecture. © 2011 IEEE.

We present two schemes for interfacing and manipulating individual atoms: One involves an array of dipole-traps using a spatial light modulator. The other implements cavitybased single photon generation combined with photon storage. © 2010 Optical Society of America.

We present a new scheme for trapping single atoms in separate dipole-traps and manipulating them individually. It relies on a spatial light-modulator to create the traps and will find applications in cavity-QED. © 2008 Optical Society of America.
