Abstract

Ising machines—comprising dissipatively coupled nodes capable of emulating the behaviour of ferromagnetic spins—can form analogue computing engines that surpass the sequential processing constraints of von Neumann architectures. However, the incorporation of Ising dynamics into radio-frequency wireless technologies remains limited, especially in terms of their potential to enhance wireless sensing capabilities. Here we report a passive wireless sensor that uses Ising dynamics to accurately implement threshold sensing. The device correlates the occurrence of violations in a sensed parameter with transitions in the coupling state of two parametric oscillators acting as Ising spins. As a result, the accuracy of the device is unaffected by distortions in its input and output signals due to multipath and is less prone to clutter caused by co-site interference. We illustrate the potential of the approach in temperature threshold sensing using a microfabricated lithium niobate microelectromechanical temperature sensor to couple two radio-frequency parametric oscillators, and show that such a system allows the sensor threshold to be wirelessly reprogrammed.

无线设备中使用Ising动力学的可编程阈值传感

伊辛机器——由能够模拟铁磁自旋行为的耗散耦合节点组成——可以形成超越冯·诺伊曼架构的顺序处理约束的模拟计算引擎。然而，将Ising动力学整合到射频无线技术中仍然有限，特别是在增强无线传感能力方面。在这里，我们报告了一种无源无线传感器，它使用Ising动态来准确地实现阈值传感。该装置将被测参数中发生的违反与作为伊辛自旋的两个参数振子耦合状态的跃迁联系起来。因此，该设备的精度不受其输入和输出信号的多径畸变的影响，并且不易受到共址干扰引起的杂波的影响。我们说明了该方法在温度阈值传感中的潜力，使用微制造的铌酸锂微机电温度传感器耦合两个射频参数振荡器，并表明这样的系统允许传感器阈值无线重新编程。
