Chapter 3. Foundations of Quantum Theory II
... called a quantum channel. The word “channel” is drawn from communication theory — we are to imagine a sender who transmits the state ρ though a communication link to another party who receives the modified state E(ρ). Sometimes the word superoperator is used as a synonym for quantum channel, where “ ...

Models of wave-function collapse
... this is of course observed, for example, in the famous double-slit interference experiment. Moreover, the theory in principle makes no distinction between microscopic and macroscopic objects and predicts that large objects can also be in more than one place at the same time. But this is not what we ...

Dyson equation for diffractive scattering
... the Maslov index of the path ␣. In line with the semiclassical approximation, the double integrals in Eqs. 共2.2兲 and 共2.4兲 are frequently evaluated in stationary phase approximation. Physically this means that the paths are entering and exiting the cavity only with the discrete angles m = arcsin关m ...
