Changelog#

Version 26.6 (2025-03-21)#

Features#

  • Rename QPU chip types, based on either “crystal” or “star” architecture and number of qubits. For example, “crystal_5” or “star_6”. For “mini” chips, like “mini_crystal_20”, the number is not based on the actual number of qubits but to the chip it’s trying to “minimize” instead, like “crystal_20”. issue SW-1059

Version 26.5 (2025-03-19)#

  • Fix Parameters with element_indices having those indices duplicated in the name when deserialised

Version 26.4 (2025-03-11)#

  • Bump pulla

Version 26.3 (2025-03-05)#

  • Add new error classes designed for client-server communication via station control client.

  • Remove general RequestError and use new specific error classes instead.

Version 26.2 (2025-03-03)#

  • Fix numpy numeric types serialization in sweeps

Version 26.1 (2025-02-28)#

  • Fix protobuf deserialisation to not align SettingNode names

Version 26.0 (2025-02-27)#

Breaking changes#

  • Remove Pydantic based ParameterModel, SettingModel, SettingNodeModel, and SweepModel, and inherit Parameter, Setting, SettingNode, and Sweep from Pydantic model directly. As a result, the signature of usage has changed. issue SW-798

    • Instead of copy, model_copy (with an optional update parameter) should be used.

    • For deserialization, for now, use SettingNode.deserialize() (Pydantic native approach will be implemented later)

  • FunctionSweep and FunctionOptions has been deleted.

  • SettingNode now supports “the path notation” when inserting/getting nodes

    • Example: settings["flux.my.new.path.foo"] = SettingNode(...) adds the specified node under the specified path. Any missing subnodes will be added.

  • SettingNode and Setting now have an attribute path which will be populated by their relative path within the settings tree when inserting/creating the node. The base class will also automatically align the name of a node with its path, but there is an attribute align_name which can be set to False to not align (used e.g. in the controllers section of the EXA settings tree).

  • Remove deprecated QCMClient.get_chad and QCMClient.get_qubit_design_properties.

Features#

  • Settings can now be declared read-only by setting read_only = True when initialising the setting.

  • Modified the html representation of settings tree to support read_only settings.

  • Methods SettingNode.get_gate_node_for_locus(), SettingNode.get_gate_properties_for_locus(), SettingNode.get_default_implementation(), and SettingNode.get_locus_node_paths_for() added for accessing EXA-specific gate/characterization nodes in the settings tree.

  • Methods SettingNode.add_for_path() and get_node_for_path() that facilitate dealing with long paths in setting trees. in setting trees.

  • Sweep.options is deprecated, use Sweep.data instead. data can be still generated using different sweep options.

  • ExponentialSweep, FixedSweep, and LinearSweep are deprecated, use Sweep instead.

  • Split DataType.NUMBER to DataType.FLOAT and DataType.INT. DataType.NUMBER is now handled as a deprecated alias for DataType.FLOAT.
