Creating The NOT Gate
To stop the electron transfer chain completing, producing output signals, the input of a photon, h, is used to produce a ‘pump probe spectroscopy’ effect by promoting an electron in an electron transfer chain. The fall of the pump probe promoted electron produces an output that is quenched down an electron transfer chain.
An alternative is similar to the AND gate alternative; an input causes a change in molecule structure breaking the electron transfer chain by not allowing the smooth energy transfer of electrons.

Famous quotes containing the words creating the, creating and/or gate:
“No one is ahead of his time, it is only that the particular variety of creating his time is the one that his contemporaries who are also creating their own time refuse to accept.... For a very long time everybody refuses and then almost without a pause almost everybody accepts. In the history of the refused in the arts and literature the rapidity of the change is always startling.”
—Gertrude Stein (1874–1946)
“The peace loving nations must make a concerted effort in opposition to those violations of treaties and those ignorings of humane instincts which today are creating a state of international anarchy and instability from which there is no escape through mere isolation or neutrality.... When an epidemic of physical disease starts to spread, the community approves and joins in a quarantine of the patients in order to protect the health of the community against the spread of the disease.”
—Franklin D. Roosevelt (1882–1945)
“Leave now
The shut gate and the decomposing wall:
The gentle serpent, green in the mulberry bush,
Riots with his tongue through the hush
Sentinel of the grave who counts us all!”
—Allen Tate (1899–1979)
