A constant lower bound for any quantum protocol for secure function evaluation
Sarah Osborn, Jamie Sikora
Secure function evaluation is a two-party cryptographic primitive where Bob computes a function of Alice's and his respective inputs, and both hope to keep their inputs private fro…
A fidelity measure for quantum states based on the matrix geometric mean
Sam Cree, Jamie Sikora
Uhlmann's fidelity function is one of the most widely used similarity measures in quantum theory. One definition of this function is that it is the minimum classical fidelity assoc…
Fundamental limitations to local energy extraction in quantum systems
Álvaro M. Alhambra, Georgios Styliaris, Nayeli A. Rodriguez-Briones +2
We examine when it is possible to locally extract energy from a bipartite quantum system in the presence of strong coupling and entanglement, a task which is expected to be restric…
On the impossibility of coin-flipping in generalized probabilistic theories via discretizations of semi-infinite programs
Jamie Sikora, John H. Selby
Coin-flipping is a fundamental cryptographic task where a spatially separated Alice and Bob wish to generate a fair coin-flip over a communication channel. It is known that ideal c…
How to make unforgeable money in generalised probabilistic theories
John H. Selby, Jamie Sikora
We discuss the possibility of creating money that is physically impossible to counterfeit. Of course, "physically impossible" is dependent on the theory that is a faithful descript…
