A photon source, comprising a first semiconductor region having excess carriers with a first conductivity type, and a second semiconductor region having excess carriers with a second conductivity type, the first and second conductivity types being opposing conductivity types; means for creating a surface acoustic wave (SAW) travelling from the first semiconductor region to the second semiconductor region such that excess carriers from the first semiconductor region are carried by the wave to the second region and quantizing means for quantizing the carrier transport caused by the wave, such that the number of carriers introduced into the second semiconductor region can be controlled to the accuracy of a single carrier.
