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.
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.

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.
Abstract: Quantum deep reinforcement learning is an integration of the principles of quantum computing with deep reinforcement learning in an effort to advance robot navigation tasks. Due to the explosion of the state and action spaces, traditionally DRL methods are limited in scalability and efficiency. QDRL, however, uses quantum superposition and entanglement for more efficient processing of big amounts of information-it enables robots to learn optimal policies for navigating complex environments. We introduce here a new QDRL framework in which quantum neural networks encode policy functions and value estimates. We demonstrate how quantum circuits can take advantage of multi-dimensional state representations in order to strengthen the power of a robot in changing its environment over time. Benchmark experiments on navigation tasks reflect phenomenal acceleration in learning performance along with better decision-making accuracy compared to classical DRL methods. We then consider integrating such quantum algorithms, as Grover's search, to improve exploration strategies in sparse reward settings. The experiments show that QDRL speeds up convergence rates and provides robots with the possibility to react more rapidly to unexpected obstacles. It discusses new applications for quantum computing of autonomous systems, potentially applied to robotics, autonomous vehicles, and other environments which require complex decision making. Some lines of work in the future are optimization of the resources needed for quantum computers and hybrid architectures for the resolution of classical problems in navigation
Quantum networks attract increasing attention due to their unique advantages over classical networks. However, the challenge of efficiently and economically constructing reliable wide-area quantum networks remains unresolved. This problem, termed network planning, is typically modeled as an Integer Linear Programming (ILP) problem. Existing solver-based solutions for classical networks face scalability issues, while heuristic approaches that sacrifice optimality for scalability heavily rely on human expertise and lack generalizability. Recently, deep reinforcement learning (DRL) has demonstrated potential in adaptive decision-making for classical network planning. However, quantum networks introduce unique constraints due to their end-to-end entanglement distribution requirements. To address this, we propose a two-stage quantum network resource allocation framework, QPLAN, that combines multi-agent DRL with traditional optimization solvers. Our approach uses a novel multi-agent reinforcement learning strategy using graph neural networks (GNNs) and transformers for traffic flow and corresponding hardware resource allocation to minimize hardware cost while cooperatively satisfying problem constraints as much as possible. The output of the DRL algorithm is then used as an initial input to prune the solution space, "warm-starting" the ILP solver and further improving the solution. This hybrid approach effectively reduces manual effort and enhances scalability. Experimental results show that our method yields near-optimal solutions with better scalability than only using ILP solvers.
