Tomographic reconstruction of the single-photon Fock state by high-frequency homodyne detection

Tomographic reconstruction of the single-photon Fock state by high-frequency homodyne detection

A single-photon Fock state has been generated by means of conditional preparation from a two-photon state emitted in the process of spontaneous parametric down-conversion. A recently developed high-frequency homodyne tomography technique has been used to completely characterize the Fock state by means of a pulse-to-pulse analysis of the detectors' difference …
