Acquire¶

class Acquire(duration, channel, mem_slot=None, reg_slot=None, kernel=None, discriminator=None, name=None)[source]¶

Bases : qiskit.pulse.instructions.instruction.Instruction

The Acquire instruction is used to trigger the ADC associated with a particular qubit; e.g. instantiated with AcquireChannel(0), the Acquire command will trigger data collection for the channel associated with qubit 0 readout. This instruction also provides acquisition metadata:

the number of cycles during which to acquire (in terms of dt),

the register slot to store classified, intermediary readout results,

the memory slot to return classified results,

the kernel to integrate raw data for each shot, and

the discriminator to classify kerneled IQ points.

Create a new Acquire instruction.

Paramètres

duration (Union[int, ParameterExpression]) – Length of time to acquire data in terms of dt.
channel (AcquireChannel) – The channel that will acquire data.
mem_slot (Optional[MemorySlot]) – The classical memory slot in which to store the classified readout result.
reg_slot (Optional[RegisterSlot]) – The fast-access register slot in which to store the classified readout result for fast feedback.
kernel (Optional[Kernel]) – A Kernel for integrating raw data.
discriminator (Optional[Discriminator]) – A Discriminator for discriminating kerneled IQ data into 0/1 results.
name (Optional[str]) – Name of the instruction for display purposes.

Lève

PulseError – If channels are supplied, and the number of register and/or memory slots does not equal the number of channels.

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.
