This problem is very difficult to solve in such basic formulation and therefore several special optimization methods have been and are being developed for binary QC, especially in the last 5 years. No such efforts are known for MV QC, so far. Probabilistic calculation ...

Atomic wave packet dynamics in finite time
... packets at the centre of the finite lattice may be enclosed by pairs of band gaps. These act as mirrors between which the atomic wave packet is reflected, thereby effectively yielding a matter wave cavity. We show that long trapping times may be obtained in such a resonator and investigate the colla ...

A model of interacting partons for hadronic structure functions
... as one looked closely enough, the structure functions did not depend on the wave-length of the photon! The constituents of the proton did not have any length-scale associated with them! This phenomenon is called scaling: the constituents of the proton appeared point-like. The parton model was propo ...
