Quantum processors and sensors promise to outperform their classical counterparts. Still, they require classical control signals, which affect their operation in a highly nontrivial way. An example: electrical voltages controlling a photonic chip or a superconducting circuit. We developed a
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
Three members of the QOLO group (Dominik Koutný, Martin Bielak, Dominik Vašinka) presented video posters at the Eastern European Machine Learning Summer School (EEML). EEML summer school is a one-week summer school around core topics regarding machine learning and artificial
We would like to share the information about the counter we have recently developed for our needs in the laboratory. Countex is an FPGA-based scientific-grade counter of electronic pulses. It allows for high-speed pulse counting with temporal resolution down to
Seven members of the QOLO group (Ivo Straka, Josef Hloušek, Dominik Koutný, Radim Hošák, Vojtěch švarc, Martin Bielak, Dominik Vašinka) were selected for poster presentations at the Photonics Online Meet-up (POM). POM is an entirely free virtual conference. It aims
