Abstract Conditional addition of photons represents a crucial tool for optical quantum state engineering and it forms a fundamental building block of advanced quantum photonic devices. Here we report on experimental implementation of the conditional

Coherent interaction of a quantum system with environment usually induces quantum decoherence. However, remarkably, in certain configurations the coherent system–environment coupling can be simultaneously explored to engineer a specific dark state

This work deals with Received Pronunciation (RP), the prestige accent in England and other parts of Great Britain. It examines the perception of this accent by English and Czech respondents. It also analyses the roles RP fulfils in the two environmen
We report a single-photon Mach-Zehnder interferometer stabilized to a phase precision of 0.05 degrees over 15 hours. To lock the phase, we employ an auxiliary reference light at a different wavelength than the quantum signal. The developed phase lock

We have devised and experimentally demonstrated a direct certification of the strong non-classical character of quantum measurement devices, namely single-photon avalanche diodes and photon-number-resolving detectors.

Detection of quantum correlations in a physical system is paramount to many cutting-edge applications in quantum information processing. We tackle the problem of inferring the entanglement from incomplete measurements by employing deep neural network

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 the existing quantum non-Gaussianity criteria for quantum states to qu
