Dominik Koutný presented a talk on Deep learning of quantum entanglement as part of the Hot Topics Session at the POM23 Photonics Meetup. For more details see published paper: 10.1126/sciadv.add7131. We also presented a number of posters: R. Stárek, M.
We are thrilled to share our research on the quantification of quantum entanglement using artificial neural networks. Our approach allows us to accurately measure entanglement without requiring complete knowledge of the quantum state. By leveraging neural networks, we achieve a
Anežka and Filip defended their Master theses with distinction. Congratulations!
Our research revealed anomalous nonlinear effects in single-photon detectors, challenging established theories. Understanding and fully characterizing these effects will significantly enhance measurement accuracy in various scientific and technological applications. The results were published in Applied Physics Reviews. The preprint is
Josef Hloušek defended his PhD thesis titled Photon-number-resolving detectors and their applications in quantum optics. Congratulations! The key results of his work: J. Hloušek, I. Straka, M. Ježek, Experimental observation of anomalous supralinear response of single-photon detectors, arXiv:2109.08347. J. Hloušek,
Tříkrálová konference Olomouc 2022 – živé pokračování online setkání mladých českých a slovenských fyziků
In our new work published in Optics Express, we present a calibration method for twisted nematic liquid crystals (TNLCs) that allows accurate polarization manipulation. The calibration method does not require knowledge of parameters or a model of the constituent TNLC

Dominik Koutný and Dominik Vašinka from our group will present video posters at the MLQ2021. The goal of this online conference, taking place March 1-5, 2021, is to bring together quantum physicists with experts in computer science and machine learning,
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,
Five members of the QOLO group (Ivo Straka, Josef Hloušek, Vojtěch Švarc, Jan Grygar, Dominik Vašinka) were selected for poster presentations at the Photonics Online Meet-up (POM). POM is an entirely free virtual conference. It aims to bring together a
