High-resolution coincidence counting system for large-scale photonics applications
Josef Hloušek, Jan Grygar, Michal Dudka +1
The increasing complexity of the recent photonic experiments challenges developing efficient multi-channel coincidence counting systems with high-level functionality. Here, we repo…
Quantum non-Gaussianity certification of photon-number-resolving detectors
Jan Grygar, Josef Hloušek, Jaromír Fiurášek +1
We report on direct experimental certification of the quantum non-Gaussian character of a photon-number resolving detector. The certification protocol is based on an adaptation of…
Experimental observation of anomalous supralinear response of single-photon detectors
Josef Hloušek, Ivo Straka, Miroslav Ježek
We demonstrate a direct single-source measurement of absolute nonlinearity of single-photon detectors with unprecedented accuracy. We discover a surprising supralinear behavior of…
Direct experimental certification of quantum non-Gaussian character and Wigner function negativity of single-photon detectors
Josef Hloušek, Miroslav Ježek, Jaromír Fiurášek
Highly nonclassical character of optical quantum detectors, such as single-photon detectors, is essential for preparation of quantum states of light and a vast majority of applicat…
Feedforward-enhanced Fock state conversion with linear optics
Vojtěch Švarc, Josef Hloušek, Martina Nováková +2
Engineering quantum states of light represents a crucial task in the vast majority of photonic quantum technology applications. Direct manipulation of the number of photons in the…
Accurate detection of arbitrary photon statistics
Josef Hloušek, Michal Dudka, Ivo Straka +1
We report a measurement workflow free of systematic errors consisting of a reconfigurable photon-number-resolving detector, custom electronic circuitry, and faithful data-processin…
Faithful hierarchy of genuine -photon quantum non-Gaussian light
Lukáš Lachman, Ivo Straka, Josef Hloušek +2
Light is an essential tool for connections between quantum devices and for diagnostic of processes in quantum technology. Both applications deal with advanced nonclassical states b…
Work and information from thermal states after subtraction of energy quanta
J. Hloušek, M. Ježek, R. Filip
Quantum oscillators prepared out of thermal equilibrium can be used to produce work and transmit information. By intensive cooling of a single oscillator, its thermal energy determ…
Quantum Non-Gaussian Multiphoton Light
Ivo Straka, Lukáš Lachman, Josef Hloušek +4
We propose an experimental method of recognizing quantum non-Gaussian multiphoton states. This is a native quantum property of Fock states, the fundamental quantum states with a co…
