固态电子自旋是量子信息科学中新兴应用的关键组成部分，包括量子计算机，量子通信链路和量子传感器。然而，固态自旋是使用复杂的微波脉冲序列来控制的，这通常是使用台式电子仪器产生的。集成所需的电子器件将能够实现可扩展的低功耗和紧凑的光学可寻址量子系统。在这里，我们报告了一个集成的可重构量子控制系统，这是用来执行拉比和拉姆齐振荡测量的NV中心的钻石。该180 nm CMOS芯片在3.02 mm2的基底面内制造，功耗为80 mW，能够产生1.6 GHz至2.6 GHz的可调谐微波信号，该信号由多达4098个可重构脉冲序列调制，脉冲宽度可在10 ns至42 ms之间调节，脉冲到脉冲延迟可在18 ns至42 ms之间调节，分辨率为2.5 ns。
Solid-state electron spins are key building blocks for emerging applications in quantum information science, including quantum computers, quantum communication links, and quantum sensors. However, solid-state spins are controlled using complex microwave pulse sequences, which are typically generated using benchtop electrical instruments. Integration of the required electronics will enable realization of a scalable low-power and compact optically addressable quantum system. Here, we report an integrated reconfigurable quantum control system, which is used to perform Rabi and Ramsey oscillation measurements for an NV center in diamond. The 180nm CMOS chip, fabricated within a footprint of 3.02mm2, consumes 80 mW of power, and is capable of generating a tunable microwave signal from 1.6 GHz to 2.6 GHz modulated with a sequence of up to 4098 reconfigurable pulses with a pulse width adjustable from 10ns to 42ms and a pulse-to-pulse delay adjustable between 18 ns to 42m, at a resolution of 2.5 ns.
