SubsystemOperator¶

class SubsystemOperator(matrix, subsystems, str_label=None)[source]¶

Bases: AbstractSubsystemOperator

A concrete operator specified in terms of a matrix.

Initialize.

Parameters:

matrix – The matrix of the operator.
subsystems – The ordered subsystems representing the tensor factor system the matrix is specified on.

Methods

base_matrix()[source]¶: Return the matrix defined on the internal subsystems.

matrix(ordered_subsystems=None)¶: Build the matrix for the operator relative to the ordered subsystems.

remove_subsystems(subsystems)¶

Return operator with subsystems removed.

Components of operators with support on removed subsystems will be set to 0.

restrict_subsystems(subsystems)¶

Reduce the operator to the list of subsystems.

Components of operators with support on removed subsystems will be set to 0.
