Holonomic quantum computation with neutral atoms
... The standard paradigm of quantum computation (QC) [1] is a dynamical one: in order to manipulate the quantum state of systems encoding information, local interactions between low dimensional subsystems (qubits) are switched on and off in such a way to enact a sequence of quantum gates. On the other h ...

... And today, we don’t believe BQP contains all of NP (though not surprisingly, we can’t prove that it doesn’t) Bennett et al. 1997: “Quantum magic” won’t be enough If you throw away the problem structure, and just consider an abstract “landscape” of 2n possible solutions, then even a quantum computer ...

The relationship between entropy and information can be illustrated by a simple example: Suppose we have a box of gas, all contained a tiny region of the box, say the upper right corner. Now let it evolve in time. Of course it will disperse and diffuse ...

It is, however, more common and sensible to use fixed boundary conditions, especially for small dimensions. The wave functions then a ...
