Non-Homogeneous Quantum Computing Resource Allocation Optimization
Jincheng Zhang
Abstract
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.
