Pairs of cooperative pulses that may be used as components of a phase cycle. The pulses are designed to produce as much of the destination state as they can, and to have impurities of opposite sign. Adding the outcomes of the two experiments then destroys the impurities.
Syntax
[traj_data,fidelity,gradient]=grape_coop(phi_profile,spin_system)
Parameters
phi_profile - phase profiles of the two pulses,
concatenated horizontally
Outputs
traj_data - trajectory information structure
fidelity - cooperative fidelity measure
gradient - cooperative fidelity gradient
Examples
An example of a cooperative optimisation is available in examples/optimal_control/cooperative/state_transfer_coop.m file.
Notes
Only phase-modulated point-to-point transformations are supported.
