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…
Small sets of complementary observables
M. Grassl, D. McNulty, L. Mišta +1
Two observables are called complementary if preparing a physical object in an eigenstate of one of them yields a completely random result in a measurement of the other. We investig…
No-activation theorem for Gaussian nonclassical correlations by Gaussian operations
Ladislav Mišta, Daniel McNulty, Gerardo Adesso
We study general quantum correlations of continuous variable Gaussian states and their interplay with entanglement. Specifically, we investigate the existence of a quantum protocol…
Nonexistence of entangled continuous-variable Werner states with positive partial transpose
Daniel McNulty, Richard Tatham, Ladislav Mišta
We address an open question about the existence of entangled continuous-variable (CV) Werner states with positive partial transpose (PPT). We prove that no such state exists by sho…
Improving continuous-variable entanglement distribution by separable states
Ladislav Mišta, Natalia Korolkova
We investigate the physical mechanism behind the counterintuitive phenomenon, the distribution of continuous-variable entanglement between two distant modes by sending a third sepa…
Nonclassical correlations in continuous-variable non-Gaussian Werner states
Richard Tatham, Ladislav Mišta, Gerardo Adesso +1
We study nonclassical correlations beyond entanglement in a family of two-mode non-Gaussian states which represent the continuous-variable counterpart of two-qubit Werner states. W…
