uniqc.backend_adapter.backend_info module¶

Unified backend information data structures.

This module defines the canonical BackendInfo dataclass that all quantum cloud platforms are normalised into, plus helpers for parsing and formatting backend identifiers.

class uniqc.backend_adapter.backend_info.BackendInfo(platform, name, description='', num_qubits=0, topology=(), status='unknown', is_simulator=False, is_hardware=False, extra=<factory>, avg_1q_fidelity=None, avg_2q_fidelity=None, avg_readout_fidelity=None, coherence_t1=None, coherence_t2=None)[source]¶

Bases: object

Canonical description of a single quantum backend / chip / simulator.

One BackendInfo object corresponds to one real device or cloud simulator exposed by a platform. The object is hashable (frozen) so it can be stored in sets.

avg_1q_fidelity¶

avg_2q_fidelity¶

uniqc.backend_adapter.backend_info.parse_backend_id(identifier)[source]¶

Parse a backend identifier into (Platform, name).

Supports two forms:

platform:name (e.g. originq:HanYuan_01)
bare name (ambiguous; tries to match across all platforms)

Parameters:: identifier – Full or partial backend identifier.
Returns:: (Platform, backend_name) tuple.
Raises:: ValueError – If the format is invalid or the platform is unknown.
