Towards quantum key distribution with noisy communication sources

Adam Walton, Anne Ghesquière, David Jennings +1

A beam emitted by a displaced thermal source, incident on a beam splitter, is used as the source in a central broadcast quantum key distribution protocol. These displaced thermal s…

Infinitesimal reference frames suffice to determine the asymmetry properties of a quantum system

Rhea Alexander, Si Gvirtz-Chen, David Jennings

Symmetry principles are fundamental in physics, and while they are well understood within Lagrangian mechanics, their impact on quantum channels has a range of open questions. The…

Constraints on magic state protocols from the statistical mechanics of Wigner negativity

Nikolaos Koukoulekidis, David Jennings

Magic states are key ingredients in schemes to realize universal fault-tolerant quantum computation. Theories of magic states attempt to quantify this computational element via mon…

Estimation of correlations and non-separability in quantum channels via unitarity benchmarking

Matthew Girling, Cristina Cirstoiu, David Jennings

The ability to transfer coherent quantum information between systems is a fundamental component of quantum technologies and leads to coherent correlations within the global quantum…

Thermal state quantum key distribution

Adam Walton, Anne Ghesquière, George Brumpton +2

We analyse a central broadcast continuous variable quantum key distribution protocol in which a beam produced by a thermal source is used to create a secret key between two parties…
