A new approach for the design of logic gates that do not involve chemical inputs is presented here. This concept is based on the polarization of a light-sensitive interface. AND and OR logic gates, working with cheap reactants, which locally triggered water splitting half reactions, were designed and operated.

In this note we make a short review of constructions of n-repeated controlled unitary gates in quantum logic gates. ∗E-mail address : [email protected] 0

This paper presents a lookup table based method for switch networks and logic gates implementation. The proposed approach is able to deliver optimal transistor networks for all Boolean functions up to four inputs. Results show a new transistor count lower bound for P-class and NPN-class for four inputs logic gates.
