Summary
| Description |
English: Fredkin and Toffoli billiard ball model of an AND gate. When a single billiard ball arrives at the gate through input 0-in or 1-in, it passes through the device unobstructed and exits via 0-out or 1-out. However, if a 0-in billiard ball arrives simultaneously as a 1-in billiard ball, they collide with each other in the upper-left-hand corner of the device and redirect each other to collide again in the lower-right-hand corner of the device. One ball then exits via 1-out and the other ball exits via the lower AND-output. Thus, the presence of a ball being emitted from the AND-output is logically consistent with the output of an AND gate that takes the presence of a ball at 0-in and 1-in as inputs.
Русский: Модель бильярдного логического элемента "И" Фредкина и Тоффоли. Если один бильярдный шар попадает во вход 0 или вход 1 он беспрепятственно проходит через устройство и выходит через выход 0 или выход 1. Но если бильярдные шары прибывает одновременно через оба входа, то они сталкиваются друг с другом в верхнем левом углу устройства и изменяют траектории движения так, чтобы снова столкнуться в правом нижнем углу. устройства. Затем один из шаров выходит через выход 1, а другой шар выходит через нижний выход "И". Таким образом, шар, выходящий из выхода "И", моделирует работу логического элемента "И" входами которого являются вход 0 и вход 1. |
