- Abstract: We demonstrate photon-counting single-pixel imaging in the ultraviolet
region. Toward this target, we develop a high-performance compact single-photon
detector based on a 4H-SiC single-photon avalanche diode (SPAD), where a
tailored readout circuit with active hold-off time is designed to restrain
detector noise and operate the SPAD in free-running mode. We use structured
illumination to reconstruct 192$\times$192 compressed images at a 4 fps frame
rate. To show the superior capability of ultraviolet characteristics, we use
our single-pixel imaging system to identify and distinguish different
transparent objects under low-intensity irradiation, and image ultraviolet
light sources. The results provide a practical solution for general ultraviolet
imaging applications.

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.

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.

Quantum imaging is well-suited to study sensitive samples which require low-light conditions, like biological tissues.
In this context, interaction-free measurements (IFM) allow us infer the presence of an opaque object without the photon interacting with the sample.
Here we extend the IFM imaging schemes to multi-pixel, semi-transparent objects, by encoding the information about the pixels into an internal degree of freedom.

Digital camera pixels measure image intensities by converting incident light energy into an analog electrical current, and then digitizing it into a fixed-width binary representation.
This direct measurement method suffers from limited dynamic range and poor performance under extreme illumination.
We propose a novel intensity cue based on measuring inter-photon timing, defined as the time delay between detection of successive photons.
