Cloud-accessible quantum computing has made heterogeneous Quantum Processing Units (QPUs) available through provider platforms. These QPUs differ in qubit technology, calibration state, queueing behavior, and pricing model, making it difficult for users to choose where to run a given computation.
The arXiv paper "Quantum Broker: QoS-Aware Distribution of Quantum Computations" proposes a broker that would manage this distribution. The abstract indicates the broker is designed to be quality-of-service aware, meaning it would account for user requirements and the varying characteristics of available QPUs when routing jobs.
Because the abstract is truncated, the article does not describe the broker's architecture, evaluation, or results. It only establishes the motivation and the proposed direction: a system that intelligently matches quantum workloads to the most suitable cloud QPU. Further details would require access to the full paper.
