It is proved, with virtually full generality, that reaching equilibrium is a universal property of quantum systems: almost any subsystem in interaction with a large enough bath will reach an equilibrium state and remain close to it for almost all times.Expand

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. They… Expand

It is argued that it is nevertheless misleading to view entanglement as a key resource for quantum‐computational power, as it is necessary for any quantum algorithm to offer an exponential speed‐up over classical computation.Expand

This work finds the optimal strategy in this case and shows that quadratically fewer total measurements are needed to verify to within a given fidelity than in published results for quantum state tomography, Bell test, or fidelity estimation protocols.Expand

This work gives an analytic description of previous numerical results and generalizes them to arbitrarily high dimensionality and constructs a family of Bell inequalities for bipartite quantum systems of arbitrarily high Dimensionality which are strongly resistant to noise.Expand

Though this result raises questions about NMR quantum computation, further analysis would be necessary to assess the power of the general unitary transformations, which are indeed implemented in these experiments, in their action on separable states.Expand

We treat continuous histories within the histories approach to generalized quantum mechanics. The essential tool is the ‘‘history group:’’ the analog, within the generalized history scheme, of the… Expand

There is a deep connection between Bell nonlocality and Bayesian games, and that the same concepts appear in both fields, and some of these strategies represent equilibrium points, leading to the notion of quantum/no-signalling Nash equilibrium.Expand

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 if… Expand

A partial answer to the question why are the correlations achievable by quantum mechanics not maximal among those that preserve causality is given by showing that slightly stronger correlations would result in a world in which communication complexity becomes trivial.Expand
