Abstract

Quantum-Dot Cellular Automata (QCA) is a computational scheme utilizing the position of interacting single electrons within arrays of quantum dots ("cells") to encode and process binary information. Clocked QCA architectures can provide power gain, logic level restoration, and memory features. Using arrays of micron-sized metal dots, we experimentally demonstrate operation of a QCA latch-inverter and a two-stage shift register.

摘要

量子点细胞自动机（QCA）是一种计算方案，它利用量子点（“细胞”）阵列中相互作用的单个电子的位置来编码和处理二进制信息。时钟控制的QCA架构可以提供功率增益、逻辑电平恢复和存储功能。我们使用微米级金属点阵列，通过实验演示了QCA锁存反相器和两级移位寄存器的运行。
