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

Sage 5.0 is available
Sage is a free mathematics software system. It is built out of nearly 100 open-source packages and features a unified Python interface. There is a nice video introduction to Sage by William Stein.
Congratulations, DR Michal Mičuda!
Congratulation to Michal, who defended his thesis and earned his Ph.D. Michal is heading to start a postdoc in QOLO group at Palacky University Olomouc.
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

How many photons does it take to measure a transmittance? Sometimes less than one.
In collaboration with theoretical quantum physicists from Pavia, Italy, we have studied minimum-energy quantum reading. Here in Quantum Optics Lab Olomouc we have demonstrated some efficient reading protocols using fiber-optics interferometric setup which encodes two quantum bits in which-way degree
