• Abstract summary: The non-classicality of compound twin beams is analyzed for intensities up to hundreds of photon pairs. The use of such compound twin beams for the generation of sub-Poissonian light absorption and measurement of with sub-shot-noise precision is analyzed. A suitable theoretical model for the compound twin beams is developed to interpret the experimental data.

• Abstract: The scheme for building stronger multi-mode twin beams from a greater number of identical twin beams sufficiently weak so that single-photon sensitive on/off detectors suffice in their detection is studied. Statistical properties of these compound twin beams involving the non-classicality are analyzed for intensities up to hundreds of photon pairs. Their properties are compared with those of the genuine twin beams that require photon-number-resolving detectors in their experimental investigations. The use of such compound twin beams for the generation of sub-Poissonian light and measurement of absorption with sub-shot-noise precision is analyzed. A suitable theoretical model for the compound twin beams is developed to interpret the experimental data.

  We demonstrate the emergence of two-photon beats from the interference of a single reference photon and a photon coming from one of two thermal sources. The ultimate quantum precision in the estimation of any value of the distance between two thermal sources is achievable independently of the wavepacket spatial structure. This technique makes it an optimal candidate to important applications in microscopy, astronomy and remote sensing.

  Multi-photon interference is at the heart of photonic quantum technologies. Here, we experimentally demonstrate that detection can be implemented with a temporal resolution sufficient to interfere photons detuned on the scales necessary for cavity-based integrated photon sources. We show how time-resolved detection of non-ideal photons can be used to improve the fidelity of an entangling operation and to mitigate the reduction of computational complexity in boson sampling experiments.

  Two twin beams with a shared signal beam and separated idler beams are used to arrive at two coupled beams with anticorrelations in photon-number fluctuations.

We show that the features imprinted by the two-photon dynamics into the spectrum of resonance fluorescence are particularly sensitive to changes in the distance between emitters. This can be exploited for applications such as superresolution imaging of point-like sources.
