Experimental verification of multi-copy activation of genuine multipartite entanglement
Robert Stárek, Tim Gollerthan, Olga Leskovjanová +5
A central concept in quantum information processing is genuine multipartite entanglement (GME), a type of correlation beyond biseparability, that is, correlations that cannot be ex…
Storage and retrieval of two unknown unitary channels
Michal Sedlák, Robert Stárek, Nikola Horová +3
We address the fundamental task of converting uses of an unknown unitary transformation into a quantum state (i.e., storage) and later retrieval of the transformation. Specific…
Calibration-free single-frame super-resolution fluorescence microscopy
Anežka Dostálová, Anežka Dostálová, Dominik Vašinka +5
Molecular fluorescence microscopy is a leading approach to super-resolution and nanoscale imaging in life and material sciences. However, super-resolution fluorescence microscopy i…
Measurement-device agnostic quantum tomography
Robert Stárek, Martin Bielak, Miroslav Ježek
Characterization of quantum states and devices is paramount to quantum science and technology. The characterization consists of individual measurements, which must be precisely kno…
