Play

class Play(pulse, channel, name=None)

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.

Parameters

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

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

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

Raises

PulseError – If pulse is not a Pulse type.
