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.

• basic_block – The BasicBlock that the operation belongs to.

_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.

property generates_path_Q_output: bool

If True, this strategy compiles to instructions that generate output on Q. If False, the instructions either generate no output, or output only on path I.

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.

abstractmethod _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.

abstractmethod _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.

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.

• basic_block – The BasicBlock that the operation belongs to.

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
