A specifically designed aza-starphene molecule is presented where contacting one, two, and/or three single Al adatoms allows this molecule to function as a “3-inputs & 2-outputs” digital full adder on a Au(111) surface. Sequentially positioning single Al adatoms with atomic precision to interact with aza-starphene, inputs one classical digit per Al, which is converted to quantum information by the molecule. The intramolecular logical calculations do not require a solid-state digital full adder cascade-like architecture. The measured Boolean truth table results in part from the quantum level repulsion effect and in part from a nonlinear magnetic effect also intrinsic to the aza-starphene molecule with its contacted Al adatoms.

单分子数字全加器

提出了一种专门设计的氮杂-starphene 分子，其中接触一个、两个和/或三个单个铝吸附原子，使该分子在 Au(111) 表面上充当“3 输入和 2 输出”数字全加器。以原子精度顺序定位单个铝吸附原子以与氮杂-starphene 相互作用，每个铝输入一个经典数字，由分子转换为量子信息。分子内逻辑计算不需要固态数字全加器级联式架构。测得的布尔真值表部分来自量子级排斥效应，部分来自非线性磁效应，也是氮杂-starphene 分子及其接触的铝吸附原子所固有的。
