Acquire

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

Bases: 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.

প্যারামিটার
  • 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.

Methods
