Operational approach to quantum indistinguishability
In our recent work, we have proposed a directly measurable parameter quantifying effective indistinguishability of particles used as information carriers in quantum information transfer and processing [M.Miková et al., Phys. Rev. A 87, 042327 (2013); arXiv:1209.0908]. We experimentally tested its relevance for photons

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
