Project Superoperators¶
A module containing tools for projecting superoperators to CP, TNI, TP, and physical.
proj_choi_to_completely_positive (choi, …) |
Projects the Choi representation of a process into the nearest Choi matrix in the space of completely positive maps. |
proj_choi_to_trace_non_increasing (choi) |
Projects the Choi matrix of a process into the space of trace non-increasing maps. |
proj_choi_to_trace_preserving (choi) |
Projects the Choi representation of a process to the closest processes in the space of trace preserving maps. |
proj_choi_to_physical (choi, …) |
Projects the given Choi matrix into the subspace of Completetly Positive and either Trace Perserving (TP) or Trace-Non-Increasing maps. |
proj_choi_to_unitary (choi, check_finite) |
Compute the unitary closest to a quantum process specified by a Choi matrix. |
