Physics World

Minds, quantum measurement, and gravity

Michael Berry

Published Oct 1, 1990• 0 citations

Abstract

Roger Penrose has provoked a great deal of discussion and controversy with his recent book The Emperor's New Mind(Oxford University Press 1989). (For a summary and review of the book's arguments by Frank Tipler, see Physics World, November 1989, p45) Its main proposal is that three problems which are usually regarded as separate are actually part of the same problem, and so might eventually find a common solution.

Inside Penrose's universe

In the years following his hugely successful book The Emperor's New Mind , in which he argued that there is a quantum aspect to human consciousness, Roger Penrose has acquired a reputation among his peers for writing beautiful books that advocate controversial ideas.

Can a Human Brain be a Quantum Computer

Oleg Kupervasser, Roman Yavich

This paper is based on the book (O. Kupervasser, Application of New Cybernetics in Physics, Elsevier, 2017). Human brain has very powerful intellect. Indeed, it seems that its intellectual possibilities are much more than possibilities of usual computers using genetic algorithm and random search (A.S. Potapov, Artificial Intellect and Universal Intelligence, Polytechnics, Saint Petersburg, 2012 (in Russian).). Our brain has also such especial property as consciousness. Some researchers suppose that these properties are a result of special structures of brain. Really, may be our brain is a quantum computer (R. Penrose, The Emperor’s New Mind, Oxford University Press, New York, 1989, R. Penrose, Shadows of the Mind, Oxford University Press, New York, 1994)? We know that a quantum computer is highly parallel device with principally insuperable protection from external observation. A quantum computer can resolve some tasks that are inaccessible for usual computers. However, it can be demonstrated that continuous unstable classical computer has the same properties as a quantum computer (O. Kupervasser, Application of New Cybernetics in Physics, Elsevier, 2017). Moreover, it seems that the main properties of a brain (powerful intellect and consciousness) can be explained by invisible correlation with surround world. Similarly, clock’s gear wheel very accurately operates in spite of absence of any intellect only because the gear wheel is a part of the highly correlated clock. We usually suppose that our world is some random set of low correlated events. However, the world, may be, is some highly correlated device (L. Susskind, J. Lindesay, An Introduction to Black Holes, Information and the String Theory Revolution: The Holographic Universe, World Scientific Publishing Company, 2004). And human beings are its “gear wheels”. It seems that Big Bang theory suppose such point of view. This pure philosophical reasonings can lead to some practical conclusions. We suppose to use instead of usual random search for computers some random number generators which are in complex correlations with surround world. It can give to computers some prototype of the such especial “human intuition”, described above.

Reversibility and Irreversibility within the Quantum Formalism

T. J. Jacobs, Christian Maes

The discussion on time-reversal in quantum mechanics exists at least since Wigner's ``Uber die Operation der Zeitumkehr in der Quantenmechanik'' paper in 1932. If and how the dynamics of the quantum world is time-reversible has been the subject of many controversies. Some have seen quantum mechanics as fundamentally time-irreversible, see for example von Neumann, and some have seen in that the ultimate cause of time's arrow and second law behavior. In his best-selling book ``The Emperor's New Mind'', Roger Penrose argues similarly and concludes that ``our sought-for quantum gravity must be a time-asymmetric theory'' [p.351]. Not so long ago, we read yet about another project in Physicalia 26: to extend quantum mechanics into new fundamentally irreversible equations, thus proposing a new theory giving ``... une description fondamentale irreversible de tout systeme physique''.
