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…
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…
The optimal reordering of measurements for photonic quantum tomography
Radim Hošák, Robert Stárek, Miroslav Ježek
Quantum tomography is an essential method of the photonic technology toolbox and is routinely used for evaluation of experimentally prepared states of light and characterization of…
Experimental characterization of a non-local convertor for quantum photonic networks
Michal Mičuda, Robert Stárek, Petr Marek +6
We experimentally characterize a quantum photonic gate that is capable of converting multiqubit entangled states while acting only on two qubits. It is an important tool in large q…
