Coherent control of macroscopic quantum states in a single
... However, only optical coherent control has been realized experimentally10. A single-Cooper-pair box1 (Fig. 1) is a unique arti®cial solid-state system in the sense that: (1) although there are a large number of electrons in the metal `box' electrode, under superconductivity they all form Cooper pair ...

Field Theory on Curved Noncommutative Spacetimes
... The formulation of classical and quantum field theories on NC spacetimes has been a very active subject over the last few years, see e.g. [30]. Most of these approaches focus on free or interacting QFTs on the Moyal–Weyl deformed or κ-deformed Minkowski spacetime. In order to address physical applic ...

Finally the M-Gate collapses the mixed state and pulls out the number sought after. What is the point of searching for a number in this way? The answer is speed. If you a ...
