Description
Summary:A modified Fredkin gate is proposed as a basic building block for low-energy computing. Essentially the modified Fredkin gate is a simple crossover switch, but it has the potential to be implemented optically. It therefore appears to be a good choice as a building block for future computers. This paper shows that the modified Fredkin gate can be used to implement multi-valued logic, threshold logic and array logic. The result is that the same basic architecture can be used to implement many different logic design techniques, so that comparisons can be made between them.
