通过将其萘基分支与单个金原子接触来操纵三萘分子的量子态。一个金原子携带 1 位经典信息输入，该信息在整个分子中转换为量子信息。 Au 三萘电子相互作用引起分子电子态的可测量的能量变化，展示了 NOR 逻辑门的功能。利用扫描隧道光谱技术对单分子逻辑门的“或非”真值表进行了表征。
Quantum states of a trinaphthylene molecule were manipulated by putting its naphthyl branches in contact with single Au atoms. One Au atom carries 1-bit of classical information Input that is converted into quantum information throughout the molecule. The Au trinaphthylene electronic interactions give rise to measurable energy shifts of the molecular electronic states demonstrating a NOR logic gate functionality. The NOR truth table of the single molecule logic gate was characterized by means of scanning tunnelling spectroscopy.
