Verifying genuine multipartite entanglement of the whole from its separable parts
Michal Mičuda, Robert Stárek, Jan Provazník +2
We prove experimentally the predicted existence of a three-qubit quantum state with genuine multipartite entanglement which can be certified solely from its separable two-qubit red…
Imperfect 1-out-of-2 quantum oblivious transfer: bounds, a protocol, and its experimental implementation
Ryan Amiri, Robert Stárek, David Reichmuth +6
Oblivious transfer is an important primitive in modern cryptography. Applications include secure multiparty computation, oblivious sampling, e-voting, and signatures. Information-t…
Experimental quantum decoherence control by dark states of the environment
Robert Stárek, Michal Mičuda, Ivo Straka +5
Coherent interaction of a quantum system with environment usually induces quantum decoherence. However, remarkably, in certain configurations the coherent system-environment coupli…
Accurate polarization preparation and measurement using twisted nematic liquid crystals
Martin Bielak, Robert Stárek, Vojtěch Krčmarský +2
Generation of particular polarization states of light, encoding information in polarization degree of freedom, and efficient measurement of unknown polarization are the key tasks i…
