Aspects of generic entanglement
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 the ``…

Quantum data hiding
DP DiVincenzo, DW Leung… - IEEE Transactions on …, 2002 - ieeexplore.ieee.org
We expand on our work on quantum data hiding - hiding classical data among parties who
are restricted to performing only local quantum operations and classical communication (…

Bulk quantum computation with nuclear magnetic resonance: theory and experiment
…, MG Kubinec, DW Leung - Proceedings of the …, 1998 - royalsocietypublishing.org
We show that quantum computation is possible with mixed states instead of pure states as
inputs. This is performed by embedding within the mixed state a subspace that transforms like …

Methodology for quantum logic gate construction
We present a general method to construct fault-tolerant quantum logic gates with a simple
primitive, which is an analog of quantum teleportation. The technique extends previous results …

The entanglement of purification
We introduce a measure of both quantum as well as classical correlations in a quantum
state, the entanglement of purification. We show that the (regularized) entanglement of …

Locking classical correlations in quantum states
We show that there exist bipartite quantum states which contain a large locked classical
correlation that is unlocked by a disproportionately small amount of classical communication. In …

Oblivious remote state preparation
DW Leung, PW Shor - Physical review letters, 2003 - APS
We characterize the class of remote state preparation (RSP) protocols that use only forward
classical communication and entanglement, deterministically prepare an exact copy of a …

Hiding bits in Bell states
We present a scheme for hiding bits in Bell states that is secure even when the sharers, Alice
and Bob, are allowed to carry out local quantum operations and classical communication. …
