论文摘要
考虑到噪声和错误的无所不知，实现量子信息处理的承诺仍然是一项艰巨的任务。在嘈杂的中间尺度量子时代，适应量子力学的噪声经典计算方式可能是通往近期应用的可行途径。在这里，我们提出了单个非线性振荡器中的连续可变量子储层计算。通过对我们的模型的数值模拟，我们证明了量子古典性能的改进，并确定其可能的来源：量子测量的非线性。除了量子储层计算之外，该结果可能会影响量子机学习中结果的解释。我们研究量子储层的性能如何取决于希尔伯特空间维度，如何受到注射噪声的影响以及对其实验实现的简要评论。我们的结果表明，单个非线性振荡器中的量子储层计算是近期硬件上量子计算的有吸引力的模态。
Realizing the promise of quantum information processing remains a daunting task, given the omnipresence of noise and error. Adapting noise-resilient classical computing modalities to quantum mechanics may be a viable path towards near-term applications in the noisy intermediate-scale quantum era. Here, we propose continuous variable quantum reservoir computing in a single nonlinear oscillator. Through numerical simulation of our model we demonstrate quantum-classical performance improvement, and identify its likely source: the nonlinearity of quantum measurement. Beyond quantum reservoir computing, this result may impact the interpretation of results across quantum machine learning. We study how the performance of our quantum reservoir depends on Hilbert space dimension, how it is impacted by injected noise, and briefly comment on its experimental implementation. Our results show that quantum reservoir computing in a single nonlinear oscillator is an attractive modality for quantum computing on near-term hardware.
