Abstract

A central challenge in quantum information science and technology is achieving real-time estimation and feedforward control of quantum systems. This challenge is compounded by the inherent inhomogeneity of quantum resources, such as qubit properties and controls, and their intrinsically probabilistic nature. This leads to stochastic challenges in error detection and probabilistic outcomes in processes such as heralded remote entanglement. Given these complexities, optimizing the construction of quantum resource states is an NP-hard problem. In this paper, we address the quantum resource scheduling issue by formulating the problem and simulating it within a digitized environment, allowing the exploration and development of agent-based optimization strategies. We employ reinforcement learning agents within this probabilistic setting and introduce a new framework utilizing a Transformer model that emphasizes self-attention mechanisms for pairs of qubits. This approach facilitates dynamic scheduling by providing real-time, next-step guidance. Our method significantly improves the performance of quantum systems, achieving more than a 3$\times$ improvement over rule-based agents, and establishes an innovative framework that improves the joint design of physical and control systems for quantum applications in communication, networking, and computing.

Dynamic Quantum Network Resource Allocation Optimization

Jincheng Zhang

This paper addresses the critical challenge of optimizing resource allocation within dynamic quantum networks (QNs). The inherent complexities of QNs, including fluctuating demands, evolving topologies, and the fragility of quantum states, necessitate adaptive resource management strategies. We propose a novel algorithm leveraging reinforcement learning (RL) to dynamically adjust resource allocation based on real-time network conditions. The algorithm learns an optimal policy by iteratively interacting with a simulated QN environment, maximizing the overall quantum channel throughput while minimizing the probability of quantum error. Specifically, the core mechanism involves formulating the resource allocation problem as a Markov Decision Process (MDP), where the state represents the network's current configuration, the action represents the allocation of quantum resources (e.g., qubits, entanglement), and the reward reflects the successful completion of quantum communication tasks. The RL agent utilizes a Q-learning algorithm to estimate the optimal Q-function, guiding the allocation process. We demonstrate, through simulation, that our algorithm significantly outperforms static allocation strategies in terms of throughput and reliability, even under highly dynamic network conditions. The key contributions of this work lie in the integration of RL with the unique characteristics of QNs and the development of a practical algorithm for adaptive resource management. Further research will explore the scalability of this approach and its application to larger, more complex QN topologies.

Non-Homogeneous Quantum Computing Resource Allocation Optimization

Jincheng Zhang

This paper addresses the critical challenge of resource allocation in non-homogeneous quantum computing environments, where quantum bits (qubits) exhibit significantly varying characteristics. We propose a novel reinforcement learning-based algorithm for optimizing resource allocation, specifically designed to identify the optimal execution path for quantum computing tasks and maximize qubit utilization. The core of our approach lies in building a probabilistic model representing the quantum computing environment and employing a reinforcement learning agent to learn the best qubit allocation strategy through trial and error. This algorithm overcomes the limitations of existing methods that assume uniform qubit properties, leading to improved efficiency and success rates in quantum computations. The algorithm's core equation is as follows: * *E* = ∑i=1K *ri* (1 - *pi*) where *E* represents the overall execution efficiency, *K* is the number of qubits, *ri* is the allocated resource for qubit *i*, and *pi* is the probability of failure for qubit *i*. The algorithm's objective is to minimize *E*. Furthermore, the reward function is defined as: * R = (1 - E)* where *R* is the reward and *E* is the execution efficiency. The algorithm learns by maximizing this reward. The probabilistic model incorporates qubit characteristics such as coherence time, gate fidelity, and coupling strength, represented as probability distributions. The reinforcement learning agent utilizes a Q-learning algorithm to estimate the optimal Q-values, representing the expected reward for each state-action pair. The state space includes qubit characteristics and task requirements, while the action space consists of qubit allocation decisions. The algorithm iteratively updates its Q-values based on observed rewards, converging towards the optimal resource allocation strategy. We demonstrate that this approach offers a significant improvement over traditional uniform qubit allocation methods, particularly in scenarios with highly heterogeneous qubit populations. The primary contribution of this work is the integration of probabilistic modeling and reinforcement learning to effectively address the complexities of non-homogeneous quantum computing.

Dynamic Quantum Entanglement Resource Allocation

Jincheng Zhang

Quantum entanglement is a fundamental resource in quantum computing, enabling phenomena like super-dense coding and quantum teleportation. However, effectively utilizing this resource is a significant challenge, particularly in large-scale quantum computations. Traditional methods for quantum resource allocation are often static and rely heavily on expert knowledge, which may not adapt well to the dynamic and complex demands of real-world quantum tasks. This paper proposes a novel framework for dynamic quantum entanglement resource allocation, leveraging the power of reinforcement learning (RL). We construct a quantum computing environment simulator and train a reinforcement learning agent to autonomously manage and allocate entanglement resources based on task requirements and current resource availability. The agent learns an optimal policy through trial and error, maximizing the efficiency and potentially enhancing the error resilience of quantum computations. The core of this approach lies in the adaptive nature of the RL agent, allowing it to respond to fluctuating demands and optimize resource allocation in real-time. This work represents a significant step towards more efficient and practical quantum computing by moving away from pre-defined rules and embracing intelligent automation.

The algorithm is designed to iteratively refine its policy based on simulated quantum measurements, aiming to minimize the expected return. The exploration strategy is guided by the inherent probabilistic nature of quantum states, leading to a more diverse and potentially faster learning process. Further research is warranted to fully explore the capabilities and limitations of this approach across various RL benchmark problems.
