DRLQ: A Novel Deep Reinforcement Studying (DRL)-based Method for Job Placement in Quantum Cloud Computing Environments


The ever-evolving nature of quantum computing renders managing duties with the standard heuristic method very difficult. These fashions usually battle with adapting to the modifications and complexities of quantum computing whereas sustaining the system effectivity. Scheduling duties is essential for such techniques to scale back time wastage and useful resource administration. Present fashions are liable to position duties on unsuitable quantum computer systems, requiring frequent rescheduling as a consequence of mismatched assets. The quantum computation assets require novel methods to optimize activity completion time and scheduling effectivity.

At the moment, quantum activity placement depends on heuristic approaches or manually crafted insurance policies. Whereas sensible in sure contexts, these strategies can not exploit the total potential of dynamic quantum cloud computing environments. As quantum cloud computing integrates classical cloud assets to host functions that work together with quantum computer systems remotely, environment friendly useful resource administration turns into more and more vital.

Researchers from the College of Melbourne and Data61, CSIRO have proposed DRLQ, a novel approach primarily based on Deep Reinforcement Studying (DRL) for activity placement in quantum cloud computing environments. DRLQ leverages the Deep Q Community (DQN) structure, enhanced with the Rainbow DQN method, to create a dynamic activity placement technique. DRLQ goals to handle the constraints of conventional heuristic strategies by studying optimum activity placement insurance policies by way of steady interplay with the quantum computing atmosphere, thus enhancing activity completion effectivity and decreasing the necessity for rescheduling.

The DRLQ framework employs Deep Q Networks (DQN) mixed with the Rainbow DQN method, which integrates a number of superior reinforcement studying methods, together with Double DQN, Prioritized Replay, Multi-step Studying, Distributional RL, and Noisy Nets. These enhancements collectively enhance the coaching effectivity and effectiveness of the reinforcement studying mannequin. 

The system mannequin features a set of obtainable quantum computation nodes (QNodes) and a set of incoming quantum duties (QTasks), every with particular properties comparable to qubit quantity, circuit depth, and arrival time. The duty placement drawback is formulated as deciding on essentially the most applicable QNode for every incoming QTask to attenuate the overall response time and mitigate substitute frequency. The state area of the reinforcement studying mannequin consists of options of QNodes and QTasks, whereas the motion area is outlined because the choice of a QNode for a QTask. The reward operate is designed to attenuate the overall completion time and penalize activity rescheduling makes an attempt, encouraging the coverage to seek out optimum placements that cut back completion time and keep away from rescheduling.

Experiments performed on QSimPy simulation toolkit show that DRLQ considerably improves activity execution effectivity. The proposed technique reduces whole quantum activity completion time by 37.81% to 72.93% in comparison with different heuristic approaches. Furthermore, DRLQ successfully minimizes the necessity for activity rescheduling, reaching zero rescheduling makes an attempt in evaluations, in comparison with substantial rescheduling makes an attempt by current strategies.

In conclusion, the paper presents DRLQ, an progressive Deep Reinforcement Studying-based method for optimizing activity placement in quantum cloud computing environments. By leveraging the Rainbow DQN approach, DRLQ addresses the constraints of conventional heuristic strategies, offering a dynamic and adaptive answer for environment friendly quantum cloud useful resource administration. This method is among the first in quantum cloud useful resource administration, enabling adaptive studying and decision-making.
