Front Cover: Deterministic Nanofabrication of Quantum Dot ‐ Circular Bragg Grating Resonators with High Process Yield Using In Situ Electron Beam Lithography (Adv. Quantum Technol. 1/2026)
Abstract
The image shows a deterministically fabricated quantum-dot single-photon source integrated in a circular Bragg grating microresonator. Precise emitter placement at the resonator centre ensures efficient optical-mode coupling. A backside gold mirror yields highly directional, bright emission. The wavelength matches atom-based quantum memories, making the device a key component for scalable photonic quantum networks and integration.
