Abstract

Co-integrating a cryo-CMOS SoC with nitrogen-vacancy (NV) centers in diamond enables a scalable quantum platform. This work introduces a combined Class-DE RFDAC and class-D PDM driver for multi-qubit electron- and nuclear-spin control. A switch allows shared coil driving enabling multi-band 2.5-3.2GHz(1.9-2.1MHz), large-current 70mA(38mA), high-Rabi frequency 2.31MHz(1.93kHz) and high-fidelity 99.34(3)%(99.78(2)%) electron(nuclear) quantum logic gates with decoupled coherence times >50ms.
