- Abstract: Hong-Ou-Mandel (HOM) interference, the bunching of indistinguishable photons
at a beam splitter, is a staple of quantum optics and lies at the heart of many
quantum sensing approaches and recent optical quantum computers. Here, we
report a full-field, scan-free, quantum imaging technique that exploits HOM
interference to reconstruct the surface depth profile of transparent samples.
We demonstrate the ability to retrieve images with micrometre-scale depth
features with a photon flux as small as 7 photon pairs per frame. Using a
single photon avalanche diode camera we measure both the bunched and
anti-bunched photon-pair distributions at the HOM interferometer output which
are combined to provide a lower-noise image of the sample. This approach
demonstrates the possibility of HOM microscopy as a tool for label-free imaging
of transparent samples in the very low photon regime.

Scattering scanning near-field optical microscopy (s-SNOM) is known as a promising technique for overcoming Abbe diffraction limit.
We propose a quantum model for the suggested system, by employing electric-dipole approximation, image theory, and perturbation theory.
Our proposed scheme can be used for quantum imaging or quantum spectroscopy with high resolution.

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.

Long distance transmission of quantum information is a central ingredient of distributed quantum information processors.

We demonstrate quantum-limited transduction of millimeter-wave (mmwave) photons into optical photons using cold $85$Rb atoms as the transducer.

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.

We introduce a single-photon detector design operating in the microwave domain based on a weakly nonlinear metamaterial.
We show that the single-photon detection fidelity increases with the length of the metamaterial to approach one at experimentally realistic lengths.
In stark contrast to conventional photon detectors operating in the optical domain, the photon is not destroyed by the detection and the photon wavepacket is minimally disturbed.
