- Abstract summary: A photon number detector can be evaluated by comparing it to a multiplex of on-off detectors in a practical scenario.
The quality of the prepared state and the probability of the preparation are limited by the number of on-off detectors in the multiplex.

- Abstract: Photon number resolving detectors are the ultimate measurement of quantum
optics, which is the reason why developing the technology is getting
significant attention in recent years. With this arises the question of how to
evaluate the performance of the detectors. We suggest that performance of a
photon number detector can be evaluated by comparing it to a multiplex of
on-off detectors in a practical scenario: conditional preparation of a photon
number state. Here, both the quality of the prepared state and the probability
of the preparation are limited by the number of on-off detectors in the
multiplex, which allows us to set benchmarks that can be achieved or surpassed
by the photon number resolving detectors.

We have described an optical implementation of a measure-once one-way quantum finite automaton recognizing a well-known family of unary periodic languages.
To process input words, the automaton exploits the degree of polarization of single photons and, to reduce the acceptance error probability, a technique of confidence amplification using the photon counts is implemented.

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.

Detectors capable of resolving photon numbers have undergone a significant development recently, and this is expected to affect multiplexed periodic single-photon sources.
We analyze various spatially and time-multiplexed periodic single-photon source arrangements with photon-number-resolving detectors.
We find that the highest single-photon probability is 0.907 that can be achieved by binary bulk time multiplexers using photon-number-resolving detectors.
