摘要：

We use cascaded two-photon emission from a single quantum dot in order to double the efficient transmission rate in a quantum key distribution protocol. The energetically nondegenerate photons are separated with a single-photon add/drop filter based on a Michelson interferometer. Time correlation measurements are discussed and compared with numerical simulations.
