Detailed Description

Contains helpers for the Mode bundle.

Function Documentation

const StateVector mode::coherent	(	const dcomp &	alpha,
		size_t	cutoff
	)

Coherent state.

The implementation relies on mathutils::coherentElement, which works also for high Fock-state elements

Note

The user has to take care that alpha is not too large for the given cutoff (rule of thumb: cutoff>|alpha|^2)

Parameters

alpha	amplitude
cutoff	cutoff
