AI总结:

针对金刚石NV中心量子传感器小型化中发光检测受限的问题,研究采用CMOS器件实现NV系综PDMR,达到50飞安低噪声数字化读出,适用于多模式量子传感,补上了紧凑型金刚石量子传感器的关键组件。

摘要:

基于金刚石中氮-空位(NV)中心的量子传感器正从科学探索快速迈向第一代商业应用。尽管在开发适用于NV中心自旋态操控的方法方面已取得显著进展,但缺陷发光的检测迄今仍限制着小型化传感器架构的性能。近期开发的NV中心自旋态光电检测技术为规避这些限制提供了途径,但截至目前,该技术需要研究级低电流放大器来检测从这些系统获得的皮安级电流。本文报道了采用互补金属氧化物半导体(CMOS)器件实现的NV系综磁共振光电检测(PDMR)。该集成电路可输出金刚石传感器的数字化结果,具有低噪声和50飞安的分辨率。这种集成为紧凑型金刚石基量子传感器的实现补上了最后一块缺失的组件。该器件适用于连续波(CW)和脉冲两种工作模式。我们通过高达数兆赫的直流和交流磁测量、相干自旋旋转以及用于量子传感的多轴解耦序列,验证了其功能。

英文摘要:

Quantum sensors based on the nitrogen-vacancy (NV) centre in diamond are rapidly advancing from scientific exploration towards the first generation of commercial applications. While significant progress has been made in developing suitable methods for the manipulation of the NV centre spin state, the detection of the defect luminescence has so far limited the performance of miniaturized sensor architectures. The recent development of photoelectric detection of the NV centre's spin state offers a path to circumvent these limitations, but has to-date required research-grade low current amplifiers to detect the picoampere-scale currents obtained from these systems. Here we report on the photoelectric detection of magnetic resonance (PDMR) with NV ensembles using a complementary metal-oxide semiconductor (CMOS) device. The integrated circuit delivers a digitized output of the diamond sensor with low noise and 50 femtoampere resolution. This integration provides the last missing component on the path to a compact, diamond-based quantum sensor. The device is suited for continuous wave (CW) as well as pulsed operation. We demonstrate its functionality with DC and AC magnetometry up to several megahertz, coherent spin rotation and multi-axial decoupling sequences for quantum sensing.
