Call#

class qiskit.pulse.instructions.Call(subroutine, value_dict=None, name=None)[소스]#

기반 클래스: Instruction

Pulse Call instruction.

The Call instruction represents the calling of a referenced subroutine (schedule). It enables code reuse both within the pulse representation and hardware (if supported).

Define new subroutine.

참고

Inline subroutine is mutable. This requires special care for modification.

버전 0.25.0부터 폐지됨: The class qiskit.pulse.instructions.call.Call is deprecated as of qiskit-terra 0.25.0. It will be removed no earlier than 3 months after the release date. Instead, use the pulse builder function qiskit.pulse.builder.call(subroutine) within an active building context.

매개변수:
예외 발생:

PulseError – If subroutine is not valid data format.

Attributes

arguments#

Parameters dictionary to be assigned to subroutine.

channels#

Returns the channels that this schedule uses.

duration#

Duration of this instruction.

id#

Unique identifier for this instruction.

instructions#

Iterable for getting instructions from Schedule tree.

name#

Name of this instruction.

operands#

Return instruction operands.

parameters#

Unassigned parameters which determine the instruction behavior.

prefix = 'call'#
start_time#

Relative begin time of this instruction.

stop_time#

Relative end time of this instruction.

subroutine#

Return attached subroutine.

반환:

The program referenced by the call.

반환 형식:

program (Union[Schedule, ScheduleBlock])

Methods

append(schedule, name=None)#

Return a new Schedule with schedule inserted at the maximum time over all channels shared between self and schedule.

매개변수:

  • schedule (Union['Schedule', 'Instruction']) – Schedule or instruction to be appended

  • name (str | None) – Name of the new schedule. Defaults to name of self

반환:

A new schedule with schedule a this instruction at t=0.

반환 형식:

Schedule

assigned_subroutine()[소스]#

Returns this subroutine with the parameters assigned.

참고

This function may be often called internally for class equality check despite its overhead of parameter assignment. The subroutine with parameter assigned is cached based on .argument hash. Once this argument is updated, new assigned instance will be returned. Note that this update is not mutable operation.

반환:

Attached program.

반환 형식:

program (Union[Schedule, ScheduleBlock])

ch_duration(*channels)#

Return duration of the supplied channels in this Instruction.

매개변수:

*channels (List[Channel]) – Supplied channels

반환 형식:

int

ch_start_time(*channels)#

Return minimum start time for supplied channels.

매개변수:

*channels (List[Channel]) – Supplied channels

반환 형식:

int

ch_stop_time(*channels)#

Return maximum start time for supplied channels.

매개변수:

*channels (List[Channel]) – Supplied channels

draw(dt=1, style=None, filename=None, interp_method=None, scale=1, plot_all=False, plot_range=None, interactive=False, table=True, label=False, framechange=True, channels=None)#

Plot the instruction.

버전 0.23.0부터 폐지됨: The method qiskit.pulse.instructions.instruction.Instruction.draw() is deprecated as of qiskit-terra 0.23.0. It will be removed no earlier than 3 months after the release date. No direct alternative is being provided to drawing individual pulses. But, instructions can be visualized as part of a complete schedule using qiskit.visualization.pulse_drawer.

매개변수:

  • dt (float) – Time interval of samples

  • style (Optional[SchedStyle]) – A style sheet to configure plot appearance

  • filename (str | None) – Name required to save pulse image

  • interp_method (Callable | None) – A function for interpolation

  • scale (float) – Relative visual scaling of waveform amplitudes

  • plot_all (bool) – Plot empty channels

  • plot_range (Tuple[float] | None) – A tuple of time range to plot

  • interactive (bool) – When set true show the circuit in a new window (this depends on the matplotlib backend being used supporting this)

  • table (bool) – Draw event table for supported instructions

  • label (bool) – Label individual instructions

  • framechange (bool) – Add framechange indicators

  • channels (List[Channel] | None) – A list of channel names to plot

반환:

A matplotlib figure object of the pulse schedule

반환 형식:

matplotlib.figure

insert(start_time, schedule, name=None)#

Return a new Schedule with schedule inserted within self at start_time.

매개변수:

  • start_time (int) – Time to insert the schedule schedule

  • schedule (Union['Schedule', 'Instruction']) – Schedule or instruction to insert

  • name (str | None) – Name of the new schedule. Defaults to name of self

반환:

A new schedule with schedule inserted with this instruction at t=0.

반환 형식:

Schedule

is_parameterized()#

Return True iff the instruction is parameterized.

반환 형식:

bool

shift(time, name=None)#

Return a new schedule shifted forward by time.

매개변수:

  • time (int) – Time to shift by

  • name (str | None) – Name of the new schedule. Defaults to name of self

반환:

The shifted schedule.
