量子磁力计芯片
Quantum magnetometer chipAn industrially scalable, power-efficient quantum magnetometer chip based on 4H-silicon carbide (SiC) technology. It utilizes wafer-scale fabrication to optimize V2 silicon-vacancy color centers within a planar SiC waveguide for efficient excitation and fluorescence extraction, demonstrating shot-noise-limited sensitivities around 30 nT/Hz. / 基于工业级4H碳化硅技术的工业可扩展、低功耗量子磁力计芯片。利用晶圆级制造技术优化平面碳化硅波导内的V2硅空位色心，实现高效激发和荧光提取，表现出约30 nT/Hz的散粒噪声极限灵敏度。
