RelaxationNoisePass

class RelaxationNoisePass(*args, **kwargs)

Add duration dependent thermal relaxation noise after instructions.

Initialize RelaxationNoisePass.

Parameters:

• t1s – List of T1 times in seconds for each qubit.

• t2s – List of T2 times in seconds for each qubit.

• dt – Backend sample time (resolution) in seconds. This is required for converting dt-unit op durations to times in scheduled circuits.

• op_types – Optional, the operation types to add relaxation to. If None relaxation will be added to all operations.

• excited_state_populations – Optional, list of excited state populations for each qubit at thermal equilibrium. If not supplied or obtained from the backend this will be set to 0 for each qubit.

Attributes

RelaxationNoisePass.is_analysis_pass	Check if the pass is an analysis pass.
RelaxationNoisePass.is_transformation_pass	Check if the pass is a transformation pass.

Methods

RelaxationNoisePass.__call__(circuit[, ...])	Runs the pass on circuit.
RelaxationNoisePass.name()	Return the name of the pass.
RelaxationNoisePass.run(dag)	Run the LocalNoisePass pass on dag.
RelaxationNoisePass.__call__(circuit[, ...])	Runs the pass on circuit.
