Phys. Rev. Lett. 86, 3534–3537 (2001)Generation of Photon Number States on Demand via Cavity Quantum ElectrodynamicsReceived 18 August 2000; published in the issue dated 16 April 2001 Many applications in quantum information or quantum computing require radiation with a fixed number of photons. This increased the demand for systems able to produce such fields. We discuss the production of photon fields with a fixed photon number on demand. The first experimental demonstration of the device is described. This setup is based on a cavity quantum electrodynamics scheme using the strong coupling between excited atoms and a single-mode cavity field. © 2001 The American Physical Society URL:
