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,
Recently, we have looked into actively quenched SPADs and their detection statistics.
In brief: We often measure voltage in QOLO, that’s why we created a custom four-channel ADC box. There are possible three levels of use – PyQt GUI application, python module in your scripts and commanding arduino anyway you want. Details
We reported on experimental verification of quantum non-Gaussianity of a heralded single photon state with positive Wigner function [Phys. Rev. Lett. 107, 213602 (2011)]. We unambiguously demonstrated that the generated state cannot be expressed as a mixture of Gaussian states.
Linearita detekce světla Linearita detekce světla je důležitou podmínkou v řadě metrologických aplikací ale i při testování fundamentálních fyzikálních zákonů. Od lineárního optického detektoru požadujeme, aby zvýšení dopadajícího optického výkonu vedlo k přímo úměrnému zvýšení elektrického proudu či napětí na výstupu. Šum i
