基于量子点接触中弹道输运的多值逻辑门
Multi-Valued Logic Gates based on Ballistic Transport in Quantum Point Contacts
摘要：
利用串联量子点接触的弹道输运特性，设计了可处理四元数输入的多值逻辑门。逻辑门的原则，发现最小的两个四进制数输入演示。该器件是可扩展的，允许多个输入，这使得它可以找到最小的多个输入在一个单一的门操作。此外，四进制数输入的半加法器的原理进行了论证。首先，演示了一个加法器，它将两个四进制数相加并输出输入之和。其次，演示了将加法器的和表示为两个四进制数[进位（第一位）和和（第二位）]的设备。本文中提出的所有逻辑门原则上都可以扩展到允许十进制数输入的高质量QPC。
英文摘要：
Multi-valued logic gates, which can handle quaternary numbers as inputs, are developed by exploiting the ballistic transport properties of quantum point contacts in series. The principle of a logic gate that finds the minimum of two quaternary number inputs is demonstrated. The device is scalable to allow multiple inputs, which makes it possible to find the minimum of multiple inputs in a single gate operation. Also, the principle of a half-adder for quaternary number inputs is demonstrated. First, an adder that adds up two quaternary numbers and outputs the sum of inputs is demonstrated. Second, a device to express the sum of the adder into two quaternary digits [Carry (first digit) and Sum (second digit)] is demonstrated. All the logic gates presented in this paper can in principle be extended to allow decimal number inputs with high quality QPCs.
