Trojkráľová konferencia 2022
Accurate polarimetry with liquid crystals
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
QOLO presentations at the Machine Learning for Quantum 2021
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,
Certification of quantum properties of single-photon detectors
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
QOLO presentations at the Eastern European Machine Learning Summer School, 1-9 July 2020
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
Countex – a QOLO-made counter and coincidence unit
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
SPAD Counting Model
Recently, we have looked into actively quenched SPADs and their detection statistics.
High school research project on dynamic light scattering
Martin Čmel from Gymnázium Jiřího Wolkera Prostějov has participated in Students` Professional Activities (SPA) founded by the Czech Ministry of Education and annually organized by the National pedagogical institute of the Czech Republic. Martin developed a device for dynamic light
