DRLQ: A Novel Deep Reinforcement Learning (DRL)-Based Approach for Task Placement in Quantum Cloud Computing Environments

Machine Learning


Quantum computing is constantly evolving, making it extremely challenging to manage tasks with traditional heuristic approaches. These models often struggle to adapt to the changes and complexities of quantum computing while maintaining system efficiency. Task scheduling is essential to reduce time waste and resource management in such systems. Existing models tend to place tasks on inappropriate quantum computers and require frequent rescheduling due to resource mismatches. Quantum computing resources require new strategies to optimize task completion times and scheduling efficiency.

Currently, quantum task placement relies on heuristic approaches or hand-crafted policies. While practical in certain circumstances, these methods cannot exploit the full potential of dynamic quantum cloud computing environments. As quantum cloud computing consolidates classical cloud resources to host applications that interact remotely with quantum computers, efficient resource management becomes increasingly important.

Researchers from the University of Melbourne, Data61, and CSIRO have proposed DRLQ, a novel method based on deep reinforcement learning (DRL) for task placement in quantum cloud computing environments. DRLQ leverages the Deep Q Network (DQN) architecture enhanced with the Rainbow DQN approach to create a dynamic task placement strategy. DRLQ addresses the limitations of traditional heuristic methods by learning optimal task placement policies through continuous interaction with the quantum computing environment, aiming to improve task completion efficiency and reduce the need for rescheduling.

The DRLQ framework combines the Deep Q-Network (DQN) and Rainbow DQN approaches, which integrate advanced reinforcement learning techniques such as Double DQN, Prioritized Replay, Multi-step Learning, Distributional RL, and Noisy Nets. These enhancements improve the overall training efficiency and effectiveness of reinforcement learning models.

The system model contains a set of available quantum computation nodes (QNodes) and a set of quantum tasks (QTasks), each with certain properties such as number of qubits, circuit depth, and arrival time. The task placement problem is formulated as selecting the most appropriate QNode for each incoming QTask to minimize the total response time and mitigate substitution frequency. The state space of the reinforcement learning model consists of the features of QNodes and QTasks, and the action space is defined as the selection of a QNode for a QTask. The reward function is designed to minimize the total completion time and penalize attempts to reschedule a task, encouraging the policy to find an optimal placement that reduces the completion time and avoids rescheduling.

Experiments conducted on the QSimPy simulation toolkit demonstrate that DRLQ can significantly improve task execution efficiency. The proposed method reduces the total completion time of quantum tasks by 37.81%-72.93% compared to other heuristic approaches. Furthermore, DRLQ effectively minimizes the need for task rescheduling, resulting in zero rescheduling attempts in our evaluations, compared to significant rescheduling attempts by existing methods.

Conclusion,In this paper, we present DRLQ, an innovative deep reinforcement learning-based approach for optimizing task placement in quantum cloud computing environments.,By leveraging Rainbow DQN techniques, DRLQ addresses the limitations of,traditional heuristic methods and provides a dynamic,adaptive solution for efficient quantum cloud resource management.,Our approach is one of the first approaches for quantum cloud resource,management that enables adaptive learning and decision-making.
