Noiseless loss suppression in quantum optical communication
We have proposed a protocol for conditional suppression of losses in direct quantum state transmission over a lossy quantum channel. The method works by noiselessly attenuating the input state prior to transmission through a lossy channel followed by noiseless amplification
Nature Physics: Experimental estimation of the dimension of quantum systems
In collaboration with experimental and theoretical quantum physicists from Barcelona and Bristol, we have explored properties of physical systems related to the dimension of their phase space. Experimental observations are usually described using theoretical models that make assumptions about the

Making a poster with Inkscape (+template)
There is a very nice template for a scientific poster made by Felix Breuer using Inkscape, shared under Creative Commons Attribution-ShareAlike 3.0 Unported License. For many purposes it is maybe too fancy and you could find a square-panel layout more

Na foton si posvítili vědci z Katedry optiky Přírodovědecké fakulty Univerzity Palackého v Olomouci
Tým vědců kolem doc. Radima Filipa z Katedry optiky PřF UP si znovu posvítil na foton. Nejprve v prestižním americkém časopise Physical Review Letters [1] publikoval nové kritérium neklasických projevů slabých proudů fotonů, po šesti měsících pak toto kritérium v nové

Increasing efficiency of a linear-optical quantum gate using an electronic feed forward
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
