v2024.12.0

The December 2024 release of the Tergite backend.
It is compatible with the v2024.12.x release of the Tergite stack.

Added

• Added redis connection environment variables
• Added GitLab CI configuration
• Added storing of Qobj header data in the logfiles of the quantum jobs
• Qiskit dynamics simulator backend with two-qubit CZ gate ("qiskit_pulse_2q")
• Added CouplerProps to Backend Configurations
• Added the coupling_dict to the backend_config.toml

Fixed

• Fixed httpx version to 0.27.2 as 0.28.0 removes many deprecations that we were still dependent on in FastAPI testClient

Changed

• Removed the coupling_map from the backend_config.toml as it is generated on-the-fly from the coupling_dict.

v2024.09.0

The September 2024 release of the Tergite backend.
It is compatible with the v2024.09.x release of the Tergite stack.

• BREAKING CHANGE: Removed the whole general section in the executor-config.yml
• BREAKING CHANGE: Renamed executor-config.yml to quantify-config.yml
• Removed the old config files that were used for setting up automatic calibration
• Removed the script that loaded automatic calibration configurations at the start
• Moved the backend_config.toml file from /configs folder

Full Changelog: v2024.04.0...v2024.09.0

v2024.04.0

The April 2024 release of the Tergite backend.
It is compatible with the v2024.04.x release of the Tergite stack.
The Tergite release v2024.04 which merges the Tergite stack into three clear parts: front, back, client/sdks

Added

• Added storage_file lib (formerly tergite-quantify-connector-storagefile)
• Added quantum_executor service (formerly tergite-quantify-connector)
• Added the executor-config.yml and its python-based validators

Changed

• Changed the way discriminators are loaded to load from the database
• BREAKING_CHANGE: Removed hard-coded discriminators
• BREAKING_CHANGE: Removed official support for Python 3.8; Official support is now >=3.9
• BREAKING_CHANGE: Removed Labber support
• Replaced tergite-quantify-connector-storagefile package with an internal storage_file lib
• Moved unused files to archive folder
• BREAKING_CHANGE: Removed calibration and two state discrimination source code
• BREAKING_CHANGE: Replaced tergite-quantify-connector-storagefile package with an internal storage_file lib
• BREAKING_CHANGE: Merged tergite-quantify-connector into tergite-backend and renamed its service to quantum_executor
• BREAKING_CHANGE: Changed configuration of hardware to use executor-config.yml file with proper validations on loading
• BREAKING_CHANGE: Removed support for Pulsar, or any other instrument drivers other than Cluster.
  The old implementation wrongfully assumed that all these drivers have the same signature i.e. driver(name: str, identifier: str | None)
  yet SpiRack(name: str, address: str, baud_rate: int = 9600, timeout: float = 1, is_dummy: bool = False,),
  Pulsar(name: str, identifier: Optional[str] = None, port: Optional[int] = None, debug: Optional[int] = None, dummy_type: Optional[PulsarType] = None,)
Cluster(name: str, identifier: Optional[str] = None, port: Optional[int] = None, debug: Optional[int] = None, dummy_type: Optional[PulsarType] = None) are all different.
• BREAKING_CHANGE: We got rid of quantify connector’s redundant reset() method.
• BREAKING_CHANGE: Changed backend name used when querying MSS for backend properties to be equal to settings.DEFAULT_PREFIX

Fixed

• Fixed duplicate job uploads to respond with HTTP 409
