Adding Photons Without the Noise — Our team has made a significant breakthrough by experimentally preparing multiphoton-added coherent states of light, a key development in optical quantum state engineering. The findings, published in npj Quantum Information, highlight demonstrating the addition
We are thrilled to share our research on the quantification of quantum entanglement using artificial neural networks. Our approach allows us to accurately measure entanglement without requiring complete knowledge of the quantum state. By leveraging neural networks, we achieve a
Our research revealed anomalous nonlinear effects in single-photon detectors, challenging established theories. Understanding and fully characterizing these effects will significantly enhance measurement accuracy in various scientific and technological applications. The results were published in Applied Physics Reviews. The preprint is
Our work on quantum-feature certification for single-photon detectors was published in Physical Review Letters, DOI: 10.1103/PhysRevLett.126.043601, arXiv: 2101.03509. We proposed and experimentally demonstrated a procedure for direct certification of quantum non-Gaussianity and Wigner function negativity of photonic quantum detectors. Surprisingly,

In our recent work, we have proposed a directly measurable parameter quantifying eff ective 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
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
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
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
