qiskit.pulse.ScheduleBlock.get_parameters

ScheduleBlock.get_parameters(parameter_name)

Get parameter object bound to this schedule by string name.

Note that we can define different parameter objects with the same name, because these different objects are identified by their unique uuid. For example,

from qiskit import pulse, circuit

amp1 = circuit.Parameter("amp")
amp2 = circuit.Parameter("amp")

with pulse.build() as sub_prog:
    pulse.play(pulse.Constant(100, amp1), pulse.DriveChannel(0))

with pulse.build() as main_prog:
    pulse.call(sub_prog, name="sub")
    pulse.play(pulse.Constant(100, amp2), pulse.DriveChannel(0))

main_prog.get_parameters("amp")

This returns a list of two parameters amp1 and amp2.

Parameters

parameter_name (str) – Name of parameter.

Return type

List[Parameter]

Returns

Parameter objects that have corresponding name.
