Before calling this function, the schedule can contain abstract operations (gates or measurements). This function adds pulse and acquisition information with respect to ``config`` as they are expected to arrive to device (latency or distortion corrections are not taken into account). From a point of view of :ref:`sec-compilation`, this function converts a schedule defined on a quantum-circuit layer to a schedule defined on a quantum-device layer. :param schedule: The schedule to be compiled. :param config: Compilation config for :class:`~quantify_scheduler.backends.graph_compilation.QuantifyCompiler`, of which only the :attr:`.CompilationConfig.device_compilation_config` is used in this compilation step. :returns: The modified ``schedule`` with pulse information added to all gates, or the unmodified schedule if circuit to device compilation is not necessary. .. py:function:: _compile_circuit_to_device(operation: quantify_scheduler.schedules.schedule.Schedule, device_cfg: quantify_scheduler.backends.graph_compilation.DeviceCompilationConfig, device_overrides: dict) -> quantify_scheduler.schedules.schedule.Schedule _compile_circuit_to_device(operation: quantify_scheduler.operations.operation.Operation | quantify_scheduler.schedules.schedule.Schedule, device_cfg: quantify_scheduler.backends.graph_compilation.DeviceCompilationConfig, device_overrides: dict) -> quantify_scheduler.operations.operation.Operation | quantify_scheduler.schedules.schedule.Schedule .. py:function:: set_pulse_and_acquisition_clock(schedule: quantify_scheduler.schedules.schedule.Schedule, config: quantify_scheduler.backends.graph_compilation.CompilationConfig) -> quantify_scheduler.schedules.schedule.Schedule Ensures that each pulse/acquisition-level clock resource is added to the schedule, and validates the given configuration. If a pulse/acquisition-level clock resource has not been added to the schedule and is present in device_cfg, it is added to the schedule. A warning is given when a clock resource has conflicting frequency definitions, and an error is raised if the clock resource is unknown. :param schedule: The schedule to be compiled. :param config: Compilation config for :class:`~quantify_scheduler.backends.graph_compilation.QuantifyCompiler`, of which only the :attr:`.CompilationConfig.device_compilation_config` is used in this compilation step. :returns: The modified ``schedule`` with all clock resources added, or the unmodified schedule if circuit to device compilation is not necessary. :Warns: **RuntimeWarning** -- When clock has conflicting frequency definitions. :raises RuntimeError: When operation is not at pulse/acquisition-level. :raises ValueError: When clock frequency is unknown. :raises ValueError: When clock frequency is NaN. .. py:function:: _extract_clock_freqs(operation: quantify_scheduler.operations.operation.Operation | quantify_scheduler.schedules.schedule.Schedule, all_clock_freqs: dict[str, float]) -> None .. py:function:: _set_pulse_and_acquisition_clock(schedule: quantify_scheduler.schedules.schedule.Schedule, operation: quantify_scheduler.schedules.schedule.Schedule, all_clock_freqs: dict[str, float], verified_clocks: list) -> quantify_scheduler.schedules.schedule.Schedule _set_pulse_and_acquisition_clock(schedule: quantify_scheduler.schedules.schedule.Schedule, operation: quantify_scheduler.operations.operation.Operation | quantify_scheduler.schedules.schedule.Schedule, all_clock_freqs: dict[str, float], verified_clocks: list) -> quantify_scheduler.operations.operation.Operation | quantify_scheduler.schedules.schedule.Schedule Ensures that each pulse/acquisition-level clock resource is added to the schedule. :param schedule: The resources from ``operation`` are added to ``schedule`` if ``operation`` is not a ``Schedule``. :param operation: The ``operation`` to collect resources from. :param all_clock_freqs: All clock frequencies. :param verified_clocks: Already verified clocks. :returns: The modified ``operation`` with all clock resources added. .. py:function:: _valid_clock_in_schedule(clock: str, all_clock_freqs: dict[str, float], schedule: quantify_scheduler.schedules.schedule.Schedule, operation: quantify_scheduler.operations.operation.Operation) -> bool Asserts that valid clock is present. Returns whether clock is already in schedule. :param clock: Name of the clock :param all_clock_freqs: All clock frequencies :param schedule: Schedule that potentially has the clock in its resources :param operation: Quantify operation, to which the clock belongs. Only used for error message. :raises ValueError: Returns ValueError if (i) the device config is the only defined clock and contains nan values or (ii) no clock is defined. .. py:function:: _clocks_compatible(clock: str, device_cfg: quantify_scheduler.backends.graph_compilation.DeviceCompilationConfig, schedule_clock_resources: dict[str, float]) -> bool Compare device config and schedule resources for compatibility of their clocks. Clocks can be defined in the device_cfg and in the schedule. They are consistent if - they have the same value - if the clock in the device config is nan (not the other way around) These conditions are also generalized to numpy arrays. Arrays of different length are only equal if all frequencies in the device config are nan. If the clocks are inconsistent, a warning message is emitted. :param clock: Name of the clock found in the device config and schedule :param device_cfg: Device config containing the ``clock`` :param schedule_clock_resources: All clock resources in the schedule :returns: True if the clock frequencies are consistent. .. py:function:: _assert_operation_valid_device_level(operation: quantify_scheduler.operations.operation.Operation) -> None Verifies that the operation has been compiled to device level. :param operation: Quantify operation .. py:function:: _compile_multiplexed(operation: quantify_scheduler.operations.operation.Operation, qubits: Sequence[str], operation_type: str, device_cfg: quantify_scheduler.backends.graph_compilation.DeviceCompilationConfig, device_overrides: dict) -> quantify_scheduler.operations.operation.Operation | quantify_scheduler.schedules.schedule.Schedule Compiles gate with multiple qubits. Note: it updates the `operation`, if it can directly add pulse representation. .. py:function:: _compile_single_qubit(operation: quantify_scheduler.operations.operation.Operation, qubit: str, operation_type: str, device_cfg: quantify_scheduler.backends.graph_compilation.DeviceCompilationConfig, device_overrides: dict) -> quantify_scheduler.operations.operation.Operation | quantify_scheduler.schedules.schedule.Schedule Compiles gate with multiple qubits.
