A single-photon pump

Published

Author(s)

Abstract

We describe a gated quantum dot device called a single-photon pump that produces single photons on demand through the controlled tunneling of individual electrons and holes. Simulations using an InGaAs/GaAs dot show that two modes of operation are possible, with one mode particularly attractive for quantum cryptography applications because it cannot produce more than one photon per cycle.
