A tetrabenzo[a,c,j.h]phenazine molecule is functionning like a “2 input - 1 output” XOR Boolean logic gate using the quantum level repulsion effect of the Quantum Hamiltonian Computing approach. The logical inputs are performed using one aluminum atom per input. The logical output is measured by the dI/dV tunneling spectrum at +1.1 V low bias voltage. On an Au(111) surface, each Al atom is manipulated in and out of the molecule by scanning tunneling microscope molecular manipulations. This single molecule XOR gate functions without the need of cascading OR, AND and NAND gates inside its molecular structure.

四苯甲吩嗪低压单分子XOR量子哈密顿逻辑门

使用量子哈密顿计算方法的量子级排斥效应，四苯并[a，c，jh]吩嗪分子的功能类似于“ 2输入-1输出” XOR布尔逻辑门。每个输入使用一个铝原子执行逻辑输入。逻辑输出通过+1.1 V低偏置电压下的dI / dV隧穿频谱进行测量。在Au（111）表面上，每个Al原子通过扫描隧道显微镜分子操作被操纵进出分子。这种单分子XOR门的功能无需在其分子结构内部级联OR，AND和NAND门。
