Mechanical NAND Gate: A Breakthrough in Molecular Mechanical Computing
2025-04-30
This paper presents an ingenious method for constructing a NAND gate using mechanical forces. By controlling the truth values of inputs A and B, 'pushers' are guided through a series of locked pathways. Only when A and B satisfy the NAND gate logic does the clock signal pass, thus performing the logical operation. This physics-based computation opens new possibilities in molecular mechanical computing and provides new avenues for further research. A 20-minute overview video by one of the authors is also available for those wanting to learn more.
