[2024.12.1]

released on: 20th of December 2024

[2024.12.0]

released on: 11th of December 2024

Added

  • Added redis connection environment variables
  • Added GitLab CI configuration

  • 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.

[2024.09.0]

released on: 16th of September 2024

Added

  • The QuantumExecutor as abstract class to implement a backend
  • EXECUTOR_TYPE keyword in the .env variables to select the backend
  • Qiskit dynamics simulator backend with one qubit (“qiskit_pulse_1q”)
  • Added the initialization of the redis store with configuration picked from the backend_config.toml file when the execution worker starts
  • Added an initial request to update the backend information in MSS when the execution worker starts

Changed

  • BREAKING CHANGE: EXECUTOR_DATA_DIRNAME definition in the .env variables instead of general.data_dir in executor-config.yml
  • BREAKING CHANGE: Removed the whole general section in the executor-config.yml
  • BREAKING CHANGE: Renamed executor-config.yml to quantify-config.yml

  • Moved the storage, date_time, representation and logging utils to the properties lib
  • Removed the scripts folder

[2024.04.0]

released on 28th of May 2024

Initial Public Release

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
