Quantum RL enhances security in SIM-assisted wireless networks

Researchers have developed a novel hybrid quantum reinforcement learning framework, Quantum Proximal Policy Optimization (QPPO), to enhance security in SIM-assisted wireless networks. This approach addresses the challenges of high-dimensional optimization spaces and slow convergence in existing deep reinforcement learning methods. The QPPO framework integrates a parameterized quantum circuit into the actor network, improving policy representation and exploration efficiency. Simulations show QPPO significantly outperforms traditional DRL baselines, achieving higher secrecy rates and faster convergence, particularly under conditions of imperfect eavesdropper information.
