Hyper-kódování kvantových bitů a jeho využití pro kvantové počítače (Qubit hyper-encoding for quantum computers) Kódování informace do jednotlivých kvant světla, fotonů, zefektivňuje některé komunikační a výpočetní operace a umožňuje testovat základní principy budoucích kvantových počítačů. Další cestou zvýšení hustoty uložení

Photons beyond qubits 2013
It is our great pleasure to inform you that the 2nd workshop “Photons beyond qubits”, will take place in Olomouc, Czech Republic, during April 8 – April 10, 2013. The workshop will be focused on experimental investigation of quantum information
Heisenberg’s uncertainty principle with laser pointer
What happens when a collimated beam of light hits a narrow slit? For the slit that is only slightly narrower than the beam, it appears that the slit cuts out part of the beam. When the slit opening decreases, the
Experimental test of the strongly nonclassical character of a noisy squeezed single-photon state
Our paper on testing non-Gaussian character of Schroedinger’s cat state produced under realistic conditions has been published in Physical Review A [10.1103/PhysRevA.86.043813]. In collaboration with QUIN group of prof. Ulrik Andersen we have experimentally verified the quantum non-Gaussian character of
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
