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,

SPAD Counting Model
Recently, we have looked into actively quenched SPADs and their detection statistics.
Ivo Straka awarded by the prestigious Werner von Siemens Prize
The member of our team at QOLO, Ivo Straka, has received the Werner von Siemens Award for his dissertation on preparation, detection, and characterization of quantum states of light. Ivo focused on generating multiphoton states as well as light signals
Three new optical labs opened at QOLO
Three laboratories have been built, including a dedicated HVAC system (ISO8), closed water cooling circuit, and distribution of technical gases. The labs will allow for new projects in quantum optics, optical quantum technologies, light-matter interaction, digital optical information processing, and
Digital pulsebox
Our work on the arbitrary digital pulse sequence generator using delay-loop timing of a microcontroller was published in Rev. Sci. Inst. 89, 045103 (2018), https://doi.org/10.1063/1.5019685, arXiv. Any uC can be used to get timing accuracy at the level of two or
Nadační fond Univerzity Palackého podpořil Josefův projekt
Pepova stáž ve Stockholmu byla podpořena projektem Nadačního fondu UP 2018. Děkujeme Nadačnímu fondu UP za podporu mladých výzkumníků a Pepovi za uspěšnou aplikaci! “Podpořený projekt je zaměřen na vývoj a charakterizaci nového typu fotonického zdroje – kvantových teček, což
