Optimal implementation of two-qubit linear optical quantum filters
Jaromír Fiurášek, Robert Stárek, Michal Mičuda
We design optimal interferometric schemes for implementation of two-qubit linear optical quantum filters diagonal in the computational basis. The filtering is realized by interfere…
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…
Control and enhancement of interferometric coupling between two photonic qubits
R. Stárek, M. Mičuda, I. Straka +4
We theoretically investigate and experimentally demonstrate a procedure for conditional control and enhancement of an interferometric coupling between two qubits encoded into state…
Experimental replication of single-qubit quantum phase gates
M. Mičuda, R. Stárek, I. Straka +4
We experimentally demonstrate the underlying physical mechanism of the recently proposed protocol for superreplication of quantum phase gates [W. Dür, P. Sekatski, and M. Skotiniot…
