INFORMED AI researchers (AI Theory for Quantum Information and Computing) are developing theoretical and algorithmic frameworks to make quantum and AI systems scalable, resilient, and predictable, addressing challenges in resource allocation and decision-making under uncertainty. Their recent work spans quantum networking, hybrid information theory, and decision-dependent queueing models, providing essential tools for building trustworthy distributed infrastructures that will underpin next-generation AI and quantum technologies.

Each paper below addresses a different aspect of distributed intelligence: from optimizing entanglement generation in quantum networks, to extending foundational results in quantum information theory for hybrid systems, to introducing a new class of queueing models that capture decision-dependent service dynamics.
Together, they provide theoretical and practical tools for building scalable, resilient, and trustworthy distributed infrastructures, which are essential for the future of quantum technologies and AI.
Service-the-Longest-Queue Among d Choices Policy for Quantum Entanglement Switching
Authors: Guo Xian Yau, Thirupathaiah Vasantam, Gayane Vardoyan
Key Findings:
- Introduces SLQ(d) policy for resource allocation in quantum switches.
- Performance gains: Increasing d from 1 to 2 reduces response time significantly.
- Scalability: Mean-field approximations remain accurate even for small systems.
- Comparison: Slightly less efficient than JSQ(d) but better suited for quantum constraints. Importance for AI:
- Provides load-balancing strategies for distributed quantum systems.
- Enables efficient scheduling under uncertainty, relevant for AI-driven resource management in hybrid networks.

Key Findings:
- Extends Quantum Stein’s Lemma to classical–quantum channels.
- Proves reversibility of resource theories under ARNG superchannels.
- Uses diamond norm for robust distinguishability. Importance for AI:
- Establishes predictable resource conversion in hybrid systems.
- Supports trustworthy decision-making in distributed AI-quantum infrastructures.
- Enables error analysis and hypothesis testing for AI models interacting with quantum channels.
Markov Decision Processing Networks
Authors: Sanidhay Bhambay, Thirupathaiah Vasantam, Neil Walton
Key Findings:
- Introduces MDPNs to model decision-dependent service availability.
- Shows MaxWeight policy fails in these settings.
- Proposes WARP policy, proven throughput-optimal. Importance for AI:
- Bridges queueing theory and reinforcement learning for dynamic systems.
- Provides a framework for adaptive scheduling in AI-driven networks.
- Opens avenues for learning-based control in environments with evolving resources.
Why This Research Matters for AI Development
- Scalability & Efficiency: These models help AI systems manage scarce resources in large-scale, distributed environments.
- Trust & Predictability: Extending quantum resource theories ensures reliable interoperability between classical and quantum components.
- Dynamic Decision-Making: MDPNs and WARP enable AI to make foresighted, adaptive decisions in complex, uncertain systems.
- Foundation for Hybrid Systems: All three papers contribute to building heterogeneous infrastructures where AI and quantum technologies co-exist.
