class AcquisitionStrategyPartial(operation_info: qblox_scheduler.backends.types.qblox.OpInfo)

Bases: qblox_scheduler.backends.qblox.operation_handling.base.IOperationStrategy

Contains the logic shared between all the acquisitions.

Parameters:

operation_info – The operation info that corresponds to this operation.

_acq_info: qblox_scheduler.backends.types.qblox.OpInfo

bin_mode: qblox_scheduler.enums.BinMode

acq_channel

qblox_acq_index: int | None = None

qblox_acq_bin: int | None = None

bin_idx_register: str | None = None

The register used to keep track of the bin index, only not None for append mode acquisitions.

insert_qasm(qasm_program: qblox_scheduler.backends.qblox.qasm_program.QASMProgram) → None

Add the assembly instructions for the Q1 sequence processor that corresponds to this acquisition. This function calls the appropriate method to generate assembly, depending on the bin mode.

Parameters:

qasm_program – The QASMProgram to add the assembly instructions to.

reset_bin_idx_reg(qasm_program: qblox_scheduler.backends.qblox.qasm_program.QASMProgram) → None

Resets the bin index register. This is used whenever the register which keeps track of the bin (for APPEND or AVERAGE_APPEND mode) needs to be reset. Used at the beginning of the whole program, or beginning of the schedule repetitions.

Parameters:

qasm_program – The QASMProgram to add the assembly instructions to.

abstract _acquire_with_immediate_bin_index(qasm_program: qblox_scheduler.backends.qblox.qasm_program.QASMProgram) → None

Adds the assembly to the program for an acquisition with an immediate value for the bin index.

abstract _acquire_with_register_bin_index(qasm_program: qblox_scheduler.backends.qblox.qasm_program.QASMProgram) → None

Adds the assembly to the program for an acquisition with a register value for the bin index, and assembly for incrementing the bin index by 1.

property operation_info: qblox_scheduler.backends.types.qblox.OpInfo

Property for retrieving the operation info.

_get_loop_bin_modes_with_schedule_repetitions() → list[qblox_scheduler.enums.BinMode]

For QASM compilation, we need information on the outermost Schedule’s repetitions, and we handle that in the QASMProgram the same way as any other loop bin mode. So we prepend the bin mode of the outermost Schedule’s bin mode to the loop bin modes.

class SquareAcquisitionStrategy(operation_info: qblox_scheduler.backends.types.qblox.OpInfo)

Bases: AcquisitionStrategyPartial

Performs a square acquisition (i.e. without acquisition weights).

generate_data(wf_dict: dict[str, Any]) → None

Returns None as no waveform is needed.

_acquire_with_immediate_bin_index(qasm_program: qblox_scheduler.backends.qblox.qasm_program.QASMProgram) → None

Adds the assembly to the program for an acquisition with an immediate value for the bin index.

Parameters:

qasm_program – The QASMProgram to add the assembly instructions to.

_acquire_with_register_bin_index(qasm_program: qblox_scheduler.backends.qblox.qasm_program.QASMProgram) → None

Adds the assembly to the program for an acquisition with a register value for the bin index, and assembly for incrementing the bin index by 1.

Parameters:

qasm_program – The QASMProgram to add the assembly instructions to.

_acquire_square(qasm_program: qblox_scheduler.backends.qblox.qasm_program.QASMProgram, bin_idx: int | str) → None

Adds the instruction for performing acquisitions without weights playback.

Parameters:

• qasm_program – The qasm program to add the acquisition to.

• bin_idx – The bin_idx to store the result in, can be either an int (for immediates) or a str (for registers).

class WeightedAcquisitionStrategy(operation_info: qblox_scheduler.backends.types.qblox.OpInfo)

Bases: AcquisitionStrategyPartial

Performs a weighted acquisition.

Parameters:

operation_info – The operation info that corresponds to this acquisition.

waveform_index0: int | None = None

waveform_index1: int | None = None

generate_data(wf_dict: dict[str, Any]) → None

Generates the waveform data for both acquisition weights.

Parameters:

wf_dict – The dictionary to add the waveform to. N.B. the dictionary is modified in function.

_acquire_with_immediate_bin_index(qasm_program: qblox_scheduler.backends.qblox.qasm_program.QASMProgram) → None

Adds the assembly to the program for an acquisition with an immediate value for the bin index.

Parameters:

qasm_program – The QASMProgram to add the assembly instructions to.

_acquire_with_register_bin_index(qasm_program: qblox_scheduler.backends.qblox.qasm_program.QASMProgram) → None

Adds the assembly to the program for an acquisition with a register value for the bin index, and assembly for incrementing the bin index by 1. Registers will be used for the weight indexes and the bin index.

Parameters:

qasm_program – The QASMProgram to add the assembly instructions to.

class TriggerCountAcquisitionStrategy(operation_info: qblox_scheduler.backends.types.qblox.OpInfo)

Bases: AcquisitionStrategyPartial

Performs a trigger count acquisition.

Returns None as no waveform is needed.

_acquire_with_immediate_bin_index(qasm_program: qblox_scheduler.backends.qblox.qasm_program.QASMProgram) → None

Adds the assembly to the program for an acquisition with an immediate value for the bin index.

Parameters:
