Experimental demonstration of kilometer-range quantum digital signatures
Ross James Donaldson, Robert John Collins, Klaudia Kleczkowska +6
We present an experimental realization of a quantum digital signature protocol which, together with a standard quantum key distribution link, increases transmission distance to kil…
Framework for learning agents in quantum environments
Vedran Dunjko, Jacob M. Taylor, Hans J. Briegel
In this paper we provide a broad framework for describing learning agents in general quantum environments. We analyze the types of classically specified environments which allow fo…
On optimising quantum communication in verifiable quantum computing
Theodoros Kapourniotis, Vedran Dunjko, Elham Kashefi
In the absence of any efficient classical schemes for verifying a universal quantum computer, the importance of limiting the required quantum resources for this task has been highl…
Faster quantum mixing for slowly evolving sequences of Markov chains
Davide Orsucci, Hans J. Briegel, Vedran Dunjko
Markov chain methods are remarkably successful in computational physics, machine learning, and combinatorial optimization. The cost of such methods often reduces to the mixing time…
Quantum mixing of Markov chains for special distributions
Vedran Dunjko, Hans J. Briegel
The preparation of the stationary distribution of irreducible, time-reversible Markov chains is a fundamental building block in many heuristic approaches to algorithmically hard pr…
Enhanced delegated computing using coherence
Stefanie Barz, Vedran Dunjko, Florian Schlederer +3
A long-standing question is whether it is possible to delegate computational tasks securely. Recently, both a classical and a quantum solution to this problem were found. Here, we…
