- Abstract: Although heralding signals in quantum optics experiments are typically based
on the detection of exactly one photon, it has recently been theoretically
shown that heralding based on the detection of zero photons can be useful in a
number of quantum information applications. Here we describe an experimental
technique for "heralding on zero photons" using conventional single-photon
detectors and time-tagging methods. We find that detector efficiency and dark
count rates play a counterintuitive role in the ability to accurately detect
zero photons, and demonstrate these effects in an experiment that involves
heralding on zero photons in the well-known Hong-Ou-Mandel interferometer.

superconducting-nanowire single-photon detectors have witnessed two decades of great developments.
Recent research works have demonstrated proof of principle photon number resolving (PNR) SNSPDs counting 2 to 5 photons.
In this paper, we demonstrate NbTiN based SNSPDs with over 94 percent system detection efficiency, sub 11 ps timing jitter for one photon, and sub 7 ps for two photon.

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.

The ability to perform measurements to resolve photon numbers is highly desirable for a variety of quantum information applications.
In this work, we extend photon measurement into the mesoscopic regime by implementing a detection scheme based on multiplexing highly quantum-efficient transition-edge sensors.

We propose a one-dimensional generative model which efficiently generates features using an OuterProduct-layer.
This model bypasses photon transport simulation and predicts the number of photons detected by particular photon detectors at the same level of detail as theGeant4simulation.
This generative model can be used to quickly predict photon detection probability in huge liquid argon detectors like ProtoDUNE or DUNE.

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.
