论文摘要
我们分析了由两个相干耦合量子振荡器组成的量子系统的性能，并通过模拟显示，它满足了储层计算所需的两个属性：非线性和褪色的内存。我们首先表明该系统的基础状态在输入信号上应用一组非线性转换，因此可以实现神经元。然后，我们证明该系统表现出褪色的记忆，可以通过其耗散率来控制。最后，我们表明，振荡器之间的强耦合对于确保复杂的动力学并填充了物理设备数量指数的许多基础状态神经元很重要。
We analyze the properties of a quantum system composed of two coherently coupled quantum oscillators and show through simulations that it fulfills the two properties required for reservoir computing: non-linearity and fading memory. We first show that the basis states of this system apply a set of nonlinear transformations on the input signals and thus can implement neurons. We then show that the system exhibits a fading memory that can be controlled by its dissipation rates. Finally we show that a strong coupling between the oscillators is important in order to ensure complex dynamics and to populate a number of basis state neurons that is exponential in the number of physical devices.
