This paper introduces an extension of QDMI to support Multi-Cloud Federated Quantum Workflows, enabling distributed quantum applications across multiple cloud providers and on-premise quantum hardware. The architecture includes a Federation Layer, Workflow Orchestration Engine, and Unified Security Framework, aiming to reduce job completion time and improve resource utilization.
Key findings
Proposes a comprehensive extension of QDMI for multi-cloud federated quantum workflows.
Introduces a Federation Layer to extend QDMI's device abstraction to multi-provider resource pools.
Includes a Workflow Orchestration Engine for circuit cutting, dynamic scheduling, and cross-cloud load balancing.
Presents a Unified Security Framework for federated authentication and secure communication.
Demonstrates potential to reduce average job completion time by up to 47% compared to single-provider approaches.
Limitations & open questions
The proposed architecture's effectiveness is yet to be validated through experimental evaluation.
The implementation roadmap and evaluation framework are outlined but not yet executed.
