• Abstract: We experimentally demonstrate an imaging technique based on quantum noise modification after interaction with an opaque object. By using a homodyne-like detection scheme, we eliminate the detrimental effect of the camera's dark noise, making this approach particularly attractive for imaging scenarios that require weak illumination. Here, we reconstruct the image of an object illuminated with a squeezed vacuum using a total of 800 photons, utilizing less than one photon per frame on average.

  We show that a network trained to predict where the next photon could arrive is in fact solving the minimum mean square error (MMSE) denoising task. We present a new strategy for self-supervised denoising. We present a new method for sampling from the posterior of possible solutions by iteratively sampling and adding small numbers of photons to the image.

  We propose a practical photometric solution for in-the-wild inverse rendering under unknown ambient lighting.

We demonstrate by extensive experiments that our method is easy to implement, casual to set up, and consistently outperforms existing in-the-wild inverse rendering techniques.

• Infrared photon-number-resolving imager using a Skipper-CCD [0.0]
  In astronomical detection, the search for habitable exoplanets demands imaging in the infrared its atmospheres looking for biosignatures. Here we report an imaging device in the infrared wavelength range able to arbitrarily reduce the readout noise. This device allows us to image objects in a broad range of intensities within the same frame and, by reducing the readout noise to less than 0.2e$-$, to distinguish even those shapes with less than two photons per pixel, unveiling what was previously hidden in the noise.

  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.
