Abstract

We investigate an efficient scheme for generating ultraviolet single-photons s,300 nmd. The scheme combines the highly efficient single-photon four-wave mixing scheme and fast developing quantum dot singlephotons on demand source technology. We show that near maximum, entanglement between two well matched ultraslowly propagating single-photon wave packets can be achieved. This study may lead to research and development opportunities in highly efficient entanglement schemes using photons of very large frequency difference, quantum information processing, and single-photon metrology and single-photon counting sensors in the uv spectra region.
