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…
