Paper Abstract

Many schemes for optical quantum computation and long-distance quantum communication require quantum interference between indistinguishable single-photon states generated from large numbers of independent sources. Solidstate systems allow integration of such sources on a chip. It is therefore desirable to achieve multiple solid-state singlephoton sources for practical applications. We show a promising candidate for this in the single photons generated by the radiative decay processes of excitons that are bound to isolated fluorine donor impurities in ZnSe/ZnMgSe quantum well nanostructures. Donor-bound-exciton single-photon sources typically have a narrow distribution of center wavelengths, and they overcome dipole dephasing due to their fast radiative decay time. The emitter we introduce here demonstrates these advantages, showing strong potential for allowing quantum interference between single photons emitted by independent solid-state single-photon sources.
