Sub-0.1 degree phase locking of a single-photon interferometer
Vojtěch Švarc, Martina Nováková, Michal Dudka +1
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…
Deep learning of quantum entanglement from incomplete measurements
Dominik Koutný, Laia Ginés, Magdalena Moczała-Dusanowska +4
The quantification of the entanglement present in a physical system is of para\-mount importance for fundamental research and many cutting-edge applications. Currently, achieving t…
High extraction efficiency source of photon pairs based on a quantum dot embedded in a broadband micropillar cavity
Laia Ginés, Magdalena Moczała-Dusanowska, David Dlaka +9
The generation of photon pairs in single quantum dots is based on a process that is, in its nature, deterministic. However, an efficient extraction of these photon pairs from a hig…
Bidirectional deep learning of polarization transfer in liquid crystals with application to quantum state preparation
Dominik Vašinka, Martin Bielak, Michal Neset +1
Accurate control of light polarization represents a core building block in polarization metrology, imaging, and optical and quantum communications. Voltage-controlled liquid crysta…
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…
