Detailed Description

A higher order logic, which combines several lower class logic modules in order to perform measurements and manipulations of nuclear spins.

DISCLAIMER

This module has two major issues:

• a lack of proper documentation of all the methods
• usage of tasks is not implemented and therefore direct connection to all the modules is used (I tried to compress as good as possible all the part, where access to other modules occurs so that a later replacement would be easier and one does not have to search throughout the whole file.)

The state of this module is considered to be UNSTABLE.

I am currently working on that and will from time to time improve the status of this module. So if you want to use it, be aware that there might appear

drastic changes.
