Simple proof of fault tolerance in the graph-state model
Panos Aliferis, Debbie W. Leung
We consider the problem of fault tolerance in the graph-state model of quantum computation. Using the notion of composable simulations, we provide a simple proof for the existence…
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…
