The forthcoming 6G wireless systems must simultaneously achieve extreme capacity, ultralow latency, and quantum-grade security. While classical physical-layer security techniques provide probabilistic protection, free-space quantum key distribution (QKD) suffers degradation under mobile and turbulent conditions. This article introduces a quantum-enhanced reconfigurable intelligent surface (QE-RIS) framework that synergistically integrates quantum photonics with classical electromagnetic control via hierarchical AI orchestration. Our design embeds quantum-capable devices into reconfigurable intelligent surface (RIS) unit cells operating at 12.5 GHz (RF) and 850 nm (optical) wavelengths and employs a dual-loop control mechanism, a fast loop at 5 ms and a mid-loop at 50 ms, to dynamically select classical, quantum, or hybrid modes based on real-time signal-to-noise ratio (SNR) and quantum bit error rate (QBER). Monte Carlo simulations with 20 independent channel realizations demonstrate SNR gains up to 29.3 dB for RIS with $N=512$ elements and 4-bit phase quantization, QBER reductions ranging from 20% to 35% compared to free-space QKD, control latencies below 10 ms on edge-class hardware, and secure key rates exceeding 1 Mbits(-1) under moderate turbulence. In this article, we detail implementation assumptions, control information elements (IEs), and key performance indicators (KPIs) aligned with emerging standardization efforts. The proposed framework offers a rigorous and reproducible foundation for advancing quantum-enhanced wireless communications.
