Random subspaces for encryption based on a private shared Cartesian frame
Stephen D. Bartlett, Patrick Hayden, Robert W. Spekkens
A private shared Cartesian frame is a novel form of private shared correlation that allows for both private classical and quantum communication. Cryptography using a private shared…
Quantum state transformations and the Schubert calculus
Sumit Daftuar, Patrick Hayden
Recent developments in mathematics have provided powerful tools for comparing the eigenvalues of matrices related to each other via a moment map. In this paper we survey some of th…
Multiparty data hiding of quantum information
Patrick Hayden, Debbie Leung, Graeme Smith
We present protocols for multiparty data hiding of quantum information that implement all possible threshold access structures. Closely related to secret sharing, data hiding has a…
Optimal superdense coding of entangled states
Anura Abeyesinghe, Patrick Hayden, Graeme Smith +1
We present a one-shot method for preparing pure entangled states between a sender and a receiver at a minimal cost of entanglement and quantum communication. In the case of prepari…
Aspects of generic entanglement
Patrick Hayden, Debbie W. Leung, Andreas Winter
We study entanglement and other correlation properties of random states in high-dimensional bipartite systems. These correlations are quantified by parameters that are subject to t…
On the distributed compression of quantum information
Charlene Ahn, Andrew Doherty, Patrick Hayden +1
We consider the problem of distributed compression for correlated quantum sources. The classical version of this problem was solved by Slepian and Wolf, who showed that distributed…
