论文摘要
虽然回忆录中功能元件的大小变成纳米仪的顺序，甚至较小，但其动力学中的量子效应可以显着影响其运输特性，这与最新的Memristors电导定量的实验观察结果一致。这需要开发实验可实现的程序，以检测回忆录的量子性。在这里，我们制定了一种实验协议，使我们能够找到证据表明该概述者可以处于不同的综合状态状态。我们通过周期性的投影测量值模拟了量子回忆系统中诱导的非线性，观察它如何在对谐波信号的响应中出现其他光谱成分的出现。此外，当投影测量的频率与输入频率相称时，响应表明了共鸣的行为。我们证明，对这种谐波混合的观察可以用作回忆录中量子效应的实验证据。
While the size of functional elements in memristors becomes of the orders of nano-meters or even smaller, the quantum effects in their dynamics can significantly influence their transport properties, consistent with recent experimental observations of conductance quantisation in memristors. This requires the development of experimentally realizable procedures to detect quantumness of memristors. Here we developed an experimental protocol allowing us to find evidence that the memristor can be in a superposition of states with different memristivities. We simulate the nonlinearity induced in the quantum memristive system via periodic projective measurements, observing how it manifests itself in the emergence of additional spectral components in the response to the harmonic signal. Moreover, the response demonstrates a resonant behaviour when the frequency of the projective measurements commensurates with the frequency of the input. We demonstrate that observation of such harmonic mixing can be used as experimental evidence of quantum effects in memristors.
