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.

Abstract The paper gives a survey on recent experiments on the deterministic generation of photons. Experiments using Rydberg atoms in microwave cavities and trapped ions in optical cavities are discussed. The latter experiments show that lasers on the basis of single atoms are possible.

We implement a cavity quantum electrodynamics system with an electrical circuit by coupling a superconducting qubit to a transmission-line resonator. We detect the quantization of microwaves in the resonator and generate single photons on demand.
