摘要

光学可寻址电子自旋簇是量子计算、模拟和传感领域的研究热点。然而,在强耦合条件下的几十纳米的相互作用长度尺度,它们在传统的共聚焦显微镜中是无法解决的,使得单个读数有问题。这里我们表明,当使用单镜头读出技术时,组合寄存器空间的集体状态变得可访问。利用自旋对缺陷的电荷转换,利用深度神经网络建立了复杂的光子计数统计与自旋态读出之间的联系。由于分析处理的复杂性,这种方法在进一步缩放簇中组成自旋的数量时特别通用。我们进行了相关经典信号的概念验证测量,为在实际应用中使用我们的技术铺平了道路。

Readout of strongly coupled NV center-pair spin states with deep neural networks
Optically addressable electron spin clusters are of interest for quantum computation, simulation and sensing. However, with interaction length scales of a few tens of nanometers in the strong coupling regime, they are unresolved in conventional confocal microscopy, making individual readout problematic. Here we show that when using a single shot readout technique, collective states of the combined register space become accessible. By using spin to charge conversion of the defects we draw the connection between the intricate photon count statistics with spin state readout using deep neural networks. This approach is particularly versatile with further scaling the number of constituent spins in a cluster due to complexity of the analytical treatment. We perform a proof of concept measurement of the correlated classical signal, paving the way for using our technique in realistic applications.

期刊介绍: Driven by advances in technology and experimental capability, the last decade has seen the emergence of quantum technology: a new praxis for controlling the quantum world. It is now possible to engineer complex, multi-component systems that merge the once distinct fields of quantum optics and condensed matter physics. Quantum Science and Technology is a new multidisciplinary, electronic-only journal, devoted to publishing research of the highest quality and impact covering theoretical and experimental advances in the fundamental science and application of all quantum-enabled technologies.
