Abstract

Proposed herein are techniques to turn a heterogeneous quantum network into a controller-managed, intent-driven entanglement service that can support delivery of entanglement between quantum endpoints under specified statistical service objectives. A controller can compile quantum service requests into modality-aware paths, generate a time-bounded and evidence-based readiness assessment without measuring application qubits or entangled pairs allocated to the protected service, infer degradation risk from classical telemetry and quantum-derived observations obtained through protocol-required heralding measurements or measurements of separate calibration or test resources, and apply policy-bounded remediation to subsequent service attempts. Because entanglement generation and quality estimation are probabilistic, the assessment provides evidence and confidence bounds rather than a guarantee concerning any particular unmeasured quantum state. The techniques may enable distributed quantum applications to use shared quantum switches, sources, detectors, and fiber resources with greater confidence, better utilization, and auditable service-level behavior.
