Certification of quantum properties of single-photon detectors

Our work on quantum-feature certification for single-photon detectors was published in Physical Review Letters, DOI: 10.1103/PhysRevLett.126.043601, arXiv: 2101.03509. We proposed and experimentally demonstrated a procedure for direct certification of quantum non-Gaussianity and Wigner function negativity of photonic quantum detectors. Surprisingly,
