On pypi:  pip install sopy-quantum

import sopy as sp

All content is saved as vectors,

no matrix elements inconsidered

sp.operand() is a class for exponentials operations via SoP

The exp2 roughly operates as Exp[ -0.5 alpha (x - position)**2) ]

.exp2( alphas, positions )

The exp_i roughly operates as Exp[ i k x ]

.exp_i (ks)

sp.vector() is a container of many dimensions via SoP

sp.operand(sp.vector(), sp.vector()) will generate a complex valued SoP

bandlimit integrated into systems,

since the whole idea of a SoP is to write down minimal information to represent the signal.

We find the high frequency noise added by exactly sampling band-unlimited functions mess with grid computations.
