Play

class Play(pulse, channel, name=None)

Bases: Instruction

This instruction is responsible for applying a pulse on a channel.

The pulse specifies the exact time dynamics of the output signal envelope for a limited time. The output is modulated by a phase and frequency which are controlled by separate instructions. The pulse duration must be fixed, and is implicitly given in terms of the cycle time, dt, of the backend.

Create a new pulse instruction.

Parameter

• pulse (Pulse) – A pulse waveform description, such as Waveform.

• channel (PulseChannel) – The channel to which the pulse is applied.

• name (Optional[str]) – Name of the instruction for display purposes. Defaults to pulse.name.

Methods

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