Photon-number resolution with microwave Josephson photomultipliers

2023 · arXiv (Cornell University)

We study counting photons confined in a mode of a microwave resonator via repeated measurements by a Josephson photomultiplier (JPM). The considered JPM is essentially a flux-biased phase qubit operating as a single-photon detector. We …

Realistic photon-number resolution in Gaussian boson sampling

2024 · Physical Review A

Gaussian boson sampling (GBS) is a model of nonuniversal quantum computation that claims to demonstrate quantum supremacy with current technologies. This model entails sampling photocounting events from a multimode Gaussian state at the outputs of …
