Delay¶

class Delay(duration, channel, name=None)[source]¶

Bases: qiskit.pulse.instructions.instruction.Instruction

A blocking instruction with no other effect. The delay is used for aligning and scheduling other instructions.

Example

To schedule an instruction at time = 10, on a channel assigned to the variable channel, the following could be used:

sched = Schedule(name="Delay instruction example")
sched += Delay(10, channel)
sched += Gaussian(duration, amp, sigma, channel)

The channel will output no signal from time=0 up until time=10.

Create a new delay instruction.

No other instruction may be scheduled within a Delay.

Parameters

duration (Union[int, ParameterExpression]) – Length of time of the delay in terms of dt.
channel (Channel) – The channel that will have the delay.
name (Optional[str]) – Name of the delay for display purposes.

Methods

`append`	Return a new `Schedule` with `schedule` inserted at the maximum time over all channels shared between `self` and `schedule`.
`assign_parameters`	Modify and return self with parameters assigned according to the input.
`ch_duration`	Return duration of the supplied channels in this Instruction.
`ch_start_time`	Return minimum start time for supplied channels.
`ch_stop_time`	Return maximum start time for supplied channels.
`draw`	Plot the instruction.
`flatten`	Return itself as already single instruction.
`insert`	Return a new `Schedule` with `schedule` inserted within `self` at `start_time`.
`is_parameterized`	Return `True` iff the instruction is parameterized.
`shift`	Return a new schedule shifted forward by time.
