document: Deterministic single-photon source for distributed quantum networking A sequence of single photons is emitted on demand from a single three-level atom strongly coupled to a high-finesse optical cavity . The photons are generated by an adiabatically driven stimulated Raman transition between two atomic ground states , with the vacuum field of the cavity stimulating one branch of the transition , and laser pulses deterministically driving the other branch . This process is unitary and therefore intrinsically reversible , which is essential for quantum communication and networking , and the photons should be appropriate for all-optical quantum information processing
