HardwareCompilationConfig migration guide#
The HardwareCompilationConfig replaces the old-style unvalidated JSON/dict hardware configuration, and restructures the contents into "hardware_description", "hardware_options" and "connectivity" (these fields are described in detail in Hardware compilation configuration). Using this new-style class has the advantage that all mutable and backend agnostic parameters for compiling between quantum-device and control-hardware layers are grouped in "hardware_options", separated from static and backend specific parameters for compiling between control-hardware and hardware-instructions layers, which are grouped in "hardware_options" and "connectivity". In addition, the new-style configuration is validated automatically.
Here, we describe how to migrate from the old-style configuration to the new one for the current hardware backends, which each define their own HardwareCompilationConfig datastructure with backend-specific fields (e.g., QbloxHardwareCompilationConfig and ZIHardwareCompilationConfig).
Custom backends
If you have implemented a custom backend, or have added custom instruments and/or options to the Qblox or Zurich Instruments backends, you will need to define your own HardwareCompilationConfig datastructure, as is already done for the Qblox and Zurich Instruments backends.
Qblox#
The QbloxHardwareCompilationConfig inherits from the HardwareCompilationConfig and contains the following backend-specific fields:
The
QbloxHardwareDescription, which specifies the instruments that are used in the setup, along with their instrument-specific settings. For the Qblox Cluster, we refer to the Hardware description for clusters section for the allowed instrument types and settings.The
QbloxHardwareOptions, which adds some backend-specific options to the genericHardwareOptions(see Hardware options for more details).The
compilation_passesfield, which specifies the compilation passes that are used to compile the schedule. In the example below, we do not specify the compilation passes, which means that the default passes are used.
To show how to migrate, we first load an example old-style hardware configuration for the Qblox backend:
import rich
from quantify_scheduler.backends.qblox.hardware_config_transmon_old_style import hardware_config as hardware_config_transmon_old_style
rich.print(hardware_config_transmon_old_style)

This config can be migrated to the new QbloxHardwareCompilationConfig datastructure using the built-in validation method .model_validate, which will recognize the old-style config and convert it to the new-style config:
from quantify_scheduler.backends.qblox_backend import QbloxHardwareCompilationConfig
hardware_config_transmon_new_style = QbloxHardwareCompilationConfig.model_validate(
hardware_config_transmon_old_style
)
rich.print(hardware_config_transmon_new_style)

This new-style config can then be passed to the QuantumDevice in order to compile a schedule for the Qblox backend, as is shown in the Compilation section of the Tutorial: Compiling to Hardware.
The config can also be JSON serialized and deserialized using the built-in methods .model_dump_json and .model_validate_json, respectively, to make storing, visualization and modification easier.
serialized_config = hardware_config_transmon_new_style.model_dump_json(exclude_unset=True)
deserialized_config = QbloxHardwareCompilationConfig.model_validate_json(serialized_config)
Here we passed exclude_unset=True to .model_dump_json to prevent unnecessary clutter in the json (e.g. None and default settings).
Zurich Instruments#
The ZIHardwareCompilationConfig inherits from the HardwareCompilationConfig and contains the following backend-specific fields:
The
QbloxHardwareDescription, which specifies the instruments that are used in the setup, along with their instrument-specific settings. We refer to the Zurich Instruments Hardware Description section for the allowed instrument types and settings.The
ZIHardwareOptions, which adds backend-specific options to the genericHardwareOptions, see Hardware Options for more details.The
compilation_passesfield, which specifies the compilation passes that are used to compile the schedule. In the example below, we do not specify the compilation passes, which means that the default passes are used.
To show how to migrate, we first load an example old-style hardware configuration for the Zurich Instruments backend:
