Bidirectional coherent classical communication
Aram W. Harrow, Debbie W. Leung
A unitary interaction coupling two parties enables quantum communication in both the forward and backward directions. Each communication capacity can be thought of as a tradeoff be…
The Universal Composable Security of Quantum Key Distribution
M. Ben-Or, Michal Horodecki, D. W. Leung +2
The existing unconditional security definitions of quantum key distribution (QKD) do not apply to joint attacks over QKD and the subsequent use of the resulting key. In this paper,…
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…
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…
Computation by measurements: a unifying picture
Panos Aliferis, Debbie W. Leung
The ability to perform a universal set of quantum operations based solely on static resources and measurements presents us with a strikingly novel viewpoint for thinking about quan…
