Tým vědců kolem doc. Radima Filipa z Katedry optiky PřF UP si znovu posvítil na foton. Nejprve v prestižním americkém časopise Physical Review Letters  publikoval nové kritérium neklasických projevů slabých proudů fotonů, po šesti měsících pak toto kritérium v nové
We have successfully used a fast electronic feed forward to increase the success probability of a linear optical implementation of a programmable phase gate from 25% to its theoretical limit of 50% [Phys. Rev. A 85, 012305 (2012)]. The feed
We reported on experimental verification of quantum non-Gaussianity of a heralded single photon state with positive Wigner function [Phys. Rev. Lett. 107, 213602 (2011)]. We unambiguously demonstrated that the generated state cannot be expressed as a mixture of Gaussian states.
Our paper on Hadamard gate for coherent state qubits (Schroedinger cat-like states) has been published in Physical Review A as Rapid Communication [Phys. Rev. A 84, 050301(R) (2011)]. The project was done in cooperation of prof. Ulrik L. Andersen’s group
Talk ‘Quantum optics with photons, phonons and plasmons’ will be given by Ulrik L. Andersen from Technical University of Denmark (Lyngby) at Department of Optics, Faculty of Science, Palacky University (Olomouc) on Monday Oct 26, 13:00. Address: 17. listopadu 12,
We reported on experimental verification of quantum non-Gaussianity of a heralded single photon state with positive Wigner function [arXiv:1107.4305]. We unambiguously demonstrated that the generated state cannot be expressed as a mixture of Gaussian states. A sufficient information to witness
We have experimentally demonstrated a single mode Hadamard gate for coherent state qubits by using a hybrid projector system consisting of a conditional homodyne detector and a photon counter. This implementation constitutes the first step towards the demonstration of quantum
