... Gives first polynomial-time quantum algorithm for preparing Gibbs states of commuting models at high temperature. Caveat: At high temperature cluster expansion works well for computing local expectation values. (Open: How the two threshold T’s compare?) Q advantage: we get the full Gibbs state (e.g. ...

Quantum Mechanics and Chaos Theory
... to the geometry. The most intuitive example is the so-called mushroom billiard, whose geometry consists of a rectangular stem attached to semicircular cap. On this table, it is not hard to see the presence of both integrable and chaotic paths. For the first, think simply of the so-called bouncing ba ...

It follows a recipe that is almost embarrassingly simple: take a few very basic ingredients, assemble them according to well-known quantum principles (nothing e ...

Only after they have been created enough times to accumulate ample precedent would the behaviour of these novel states become lawfu ...

Testing the Dimension of Hilbert Spaces

Examples of qubit witnesses built from two-outcome measurements were recently found in [9]. We conjecture that two-outcome measurements may be s ...

It is evident from its definition that exact unitarity is lost, since we end up with a statistical mixture of states associated with different n’s. This fact leads to a modification of the Schroedinger equation for any quantum system whose evo ...

The idea is that quantum (gel) isolation phases alternate with classical signaling (sol) open phases at frequencies such as 40 ...
