Module quantum_backend 

Quantum backend abstraction for WeftOS.

EXPERIMENTAL (0.6.x). Interface only — concrete backends (quantum_pasqal, quantum_braket) are stubs until full REST + auth land in a later release.

The trait is backend-agnostic so that neutral-atom analog processors from different vendors (Pasqal Fresnel, QuEra Aquila on AWS Braket) can be swapped or chained for fallback. Shared graph → atom-position mapping lives in quantum_register.

See .planning/development_notes/pasqal-integration.md §6.1 and §13.

Structs

BackendStatus

Backend health snapshot.

EvolutionParams

Evolution parameters — the subset of the Rydberg Hamiltonian controls that both Pasqal and QuEra expose in analog mode.

JobHandle

Opaque handle to an in-flight quantum job.

QuantumResults

Measurement results from a quantum backend, normalized across vendors.

Enums

JobStatus

Job lifecycle state, normalized across vendors.

QuantumError

Errors from quantum backends.

Traits

QuantumBackend

Abstraction over neutral-atom analog quantum processors.
