Non-interactive XOR quantum oblivious transfer: optimal protocols and their experimental implementations
Lara Stroh, Nikola Horová, Robert Stárek +4
Oblivious transfer (OT) is an important cryptographic primitive. Any multi-party computation can be realised with OT as building block. XOR oblivious transfer (XOT) is a variant wh…
Experimental demonstration of optimal probabilistic enhancement of quantum coherence
Robert Stárek, Michal Mičuda, Michal Kolář +2
We theoretically and experimentally investigate conditional enhancement of overall coherence of quantum states by probabilistic quantum operations that apply to the input state a q…
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…
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…
