Timing Control of a Heralded Single Photon Emission

2012

We experimentally demonstrate controlling the emission timing of a heralded single photon from a non-degenerate optical parametric oscillator, by placing another quickly tunable cavity at the exit as a shutter.

Creation, storage, and on-demand release of optical quantum states with a negative Wigner function

2013

Highly nonclassical quantum states of light, characterized by Wigner functions with negative values, have been created so far only in a heralded fashion. In this case, the desired output emerges rarely and randomly from a quantum-state generator. An important example is the heralded production of high-purity single-photon states, typically based on some nonlinear optical interaction. In contrast, on-demand single-photon sources were also reported, exploiting the quantized level structure of matter systems. These sources, however, lead to highly impure output states, composed mostly of vacuum. While such impure states may still exhibit certain single-photon-like features such as anti-bunchin…
