Quantum mechanical evolution towards thermal equilibrium.
The circumstances under which a system reaches thermal equilibrium, and how to derive this from basic dynamical laws, has been a major question from the very beginning of thermodynamics andExpand

  • 30 January 2002
For any quantum algorithm operating on pure states, we prove that the presence of multi‐partite entanglement, with a number of parties that increases unboundedly with input size, is necessary if theExpand

Nonlocal correlations as an information-theoretic resource
It is well known that measurements performed on spatially separated entangled quantum systems can give rise to correlations that are nonlocal, in the sense that a Bell inequality is violated. TheyExpand

Bell inequalities for arbitrarily high-dimensional systems.
We develop a novel approach to Bell inequalities based on a constraint that the correlations exhibited by local variable theories must satisfy. This is used to construct a family of Bell inequalitiesExpand

Multi-particle entanglement
We build, using group-theoretic methods, a genaral framework for approaching multi-particle entanglement. As far as entanglement is concerned, two states of n spin-1/2 particles are equivalent ifExpand

SEPARABILITY OF VERY NOISY MIXED STATES AND IMPLICATIONS FOR NMR QUANTUM COMPUTING
We give a constructive proof that all mixed states of N qubits in a sufficiently small neighborhood of the maximally mixed state are separable (unentangled). The construction provides an explicitExpand

Connection between Bell nonlocality and Bayesian game theory.
TLDR
We show that there is a connection between Bell nonlocality and Bayesian games, and that the same concepts appear in both fields. Expand

Optimal Verification of Entangled States with Local Measurements.
TLDR
We show that quantum state tomography, Bell test, and fidelity estimation are not optimal for verifying the fidelity of entangled 2-qubit states. Expand

Limit on nonlocality in any world in which communication complexity is not trivial.
Bell proved that quantum entanglement enables two spacelike separated parties to exhibit classically impossible correlations. Even though these correlations are stronger than anything classicallyExpand

New Limits on Fault-Tolerant Quantum Computation
TLDR
We show that quantum circuits cannot be fault-tolerant against a depolarizing noise level of thetas = (6 - 2radic2)/7 ap 45%, thereby improving on a previous bound of 50% . Expand
