The analogy between electrical circuits of two switches each and the
two Boolean operations as pointed out by Shannon (13). The proposal of
this paper, as summarized in Fig. 6, is to implement such gates in
polyatomic molecules undergoing ultrafast changes associated with
large, although reversible, reorganization in the electronic
configuration, making use of optical as well as chemically reactive
coupling phenomena. As we discuss, such couplings are well known and
controllable.
