From solid state to quantum and molecular electronics, the deepening of information processing

In information processing, with the perspective of a mainframe or a supercomputer on a chip, with the advent of molecular and quantum computing, and with the new ideas, even theories, concerning the processing of information by the human mind, we advance toward the deep roots of the nature and behaviour of information. The domain of electronic devices becomes a great realm of informational devices, comprising the chips of today and of the following years, the molecular computers, among which the ADN computers seem very promising, and even the human brain. On this scale of informational devices, of course, many other types of devices will find their place.
