Statistical properties, generation, and applications of three-mode biphoton fields with no more than one photon in each mode are discussed. Such field states have sub-Poissonian photon statistics and can be squeezed and entangled. The modes that simultaneously exhibit these properties in measurements are indicated. Two setups for generating such states via spontaneous parametric down-conversion are described. It is shown that the field states discussed in this study provide a quantum channel for teleportation, dense coding, and quantum key distribution.

The fluorescence photon emission of single molecule two-level system (TLS) simultaneously driven by the laser and electric radio frequency (RF) fields is investigated, using the generating function method developed recently. The fluorescence photon statistical properties of single molecule TLS are studied theoretically, under the single laser pulse field and the single RF pulse. Further, we can control the photon emission of two-level system.

We consider the photon statistical properties emitted from a two-level quantum system under pump–probe driving. The line shapes and Mandel's Q parameters are studied for a single quantum system based on the generating function method developed recently. The control of photon emission from a single quantum system driven simultaneously by a driven field and a tunable probe field is investigated. Our theoretical results and the experimental results are in good agreement.
