Information-processing system using reaction-diffusion dynamics in multi-medium quantum integrated circuits

我们提出了一个类似于反应-扩散系统的单电子装置，这是一个在自然界中产生各种动态现象的化学复杂系统。我们的电反应扩散装置由单电子非线性振荡器的二维阵列组成，它们通过电容耦合相互组合。计算机模拟显示，该装置产生节点电压的动画时空模式，例如，类似于细胞黏菌群的旋转螺旋模式和让我们想起细胞分裂的分裂和倍增模式。

We proposed a single-electron device that is analogous to the reaction-diffusion system, a chemical complex system producing various dynamic phenomena in the natural world. Our electrical reaction-diffusion device consists of a two-dimensional array of single-electron nonlinear oscillators that are combined with one another through capacitive coupling. Computer simulation revealed that the device produces animated spatiotemporal patterns of node voltages, e.g., a rotating spiral pattern similar to that of a colony of cellular slime molds and a dividing-and-multiplying pattern that reminds us of cell division.
