Unitary leakage suppression #44

Closed aarontrowbridge closed 11 months ago

aarontrowbridge commented 11 months ago

Problem It would be nice to have an objective to suppress unitary leakage errors. See this paper for details.

Solution A leakage suppression Objective would be ideal. It would use the complement to the target subspace to penalize leakage.

Describe alternatives you've considered This is currently implemented for states, using an L1 objective.

Additional context This is crucial feature to have when optimizing truncated systems.

see branch #leakage-suppression for solution. in future, note "create a branch" on right
