Quantum interference is known to become extinct with distinguishing information, as illustrated by the ubiquitous double-slit experiment or two-photon HOM effect. In former case single particle destroyed which-path information while in latter bunching tails-off photons distinguishable. It has been observed that when more than two particles are involved, these patterns general a non monotonic function of distinguishability. Here we perform comprehensive characterization, both theoretically...
Imaging in a broad light-intensity regime with high signal-to-noise ratio is key capability fields as diverse quantum metrology and astronomy. Achieving ratios imaging leads to surpassing the classical limit parameter estimation. In astronomical detection, search for habitable exoplanets demands of atmospheres infrared look biosignatures. These optical applications are hampered by detection noise, which critically limits their potential, thus photon-number spatial-resolution detectors. Here...
Fano noise, readout and the partial-charge-collection (PCC) effect collectively contribute to degradation of energy spectra in charge-coupled device (CCD) measurements, especially at low energies. In this work, x rays produced by fluorescence fluorine (677 eV) aluminum (1486 were recorded using a Skipper-CCD, which enabled noise be reduced $0.2\phantom{\rule{0.2em}{0ex}}{e}^{\ensuremath{-}}$. Based on an analytical description photopeak shapes resulting from convolution PCC we achieved...
Optical phase determination is an important and established tool in diverse fields such as astronomy, biology, or quantum optics. There increasing interest using a lower number of total photons. However, different noise sources, electronic readout the detector, shot noise, hamper estimation regimes very low illumination. Here we report study on how quality affected by these two sources noise. To that end, experimentally reconstruct wavefronts means point diffraction interferometer for mean...
We demonstrate the feasibility of implementing a photon source with sub-Poissonian emission statistics through temporal multiplexing continuous wave heralded in optical communications wavelength range. use time arrival information heralding to actively modify delay an all-fiber assembly, order synchronize output respect external clock. Within this synchronized operating regime we show that addition single correcting stage can improve figure merit for source. obtain brightness improvement...
Sub-shot-noise performance in transmission measurements can be achieved optical quantum metrology owing to significantly lower uncertainty light intensity of beams compared their classical counterparts. In this work, we simulate the outcome an experiment that uses a multiplexed single-photon source, considering several types experimental losses, where show sub-Poissonian statistics output is key for achieving sub-shot-noise performance. We compare numerical results with shot-noise limit...
In this work, we study the potential of using a Skipper-CCD detector in twin-beam source for preserving spatial correlations. An improvement noise reduction factor is predicted and preliminary experimental results are presented.
We present the work in progress of a proposed scheme for transmission measurement that combines quantum light with sub-Poissonian statistics novel Skipper-CCD sensors to obtain advantage ultra-low regimes.
