2.1.3. filter_functions.gradient
This module implements functions to calculate filter function and infidelity derivatives. Currently only auto-correlated noise (i.e. no cross-correlations) is implemented.
- Throughout this documentation the following notation will be used:
n_dt denotes the number of time steps,
n_cops the number of all control operators,
n_ctrl the number of accessible control operators (if identifiers are provided, otherwise n_ctrl=n_cops),
n_nops the number of noise operators,
n_omega the number of frequency samples, and
d the dimension of the system.
