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.

Optional
[RegisterSlot
]) – The fast-access register slot in which to store the classified readout result for fast feedback.kernel (

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