Abstract

In the year 2020, British physicist Roger Penrose was awarded the Nobel Prize. In this article, his main researches will be presented, focusing on his model of quantum consciousness. We show the wide spectrum of his work, as well as his boldness in several aspects related to current research in physics.

Quantum theory of consciousness

Ryszard Mirek

The nature of consciousness, its occurrence in the brain and its ultimate place in the universe are unknown. Probably the most interesting attempt to create a quantum theory of consciousness is that of Roger Penrose (recipient of the 2020 Nobel Prize for Physics) and an American anaesthesiologist Stuart Hameroff. They are both well known for their studies of consciousness and for the thesis that consciousness originates from quantum states in neural microtubules. The starting point for this article are the authors’ considerations contained in their joint work (Penrose & Hameroff, 2017). This paper also proposes an initial attempt to combine this theory with quantum logic.

Nobel Prize 2022 in Honor of Quantum Physics

Nougaoui, Abdelkrim

The Nobel Prize in Physics for the year 2022 was awarded to the three physicists: the French Alain Aspect, the American John F. Clauser and the Austrian Anton Zeilinger for their pioneering work in quantum physics experimentation. The three physicists were rewarded for their decisive experiments concerning entanglement quantum states, which will open up new horizons for the quantum computing, quantum coded-communication, quantum network etc. Thus the three physicists have highlighted the property that Einstein never wanted to admit and he has regarded it as a strange action. Quantum theory did really develop until the 1920s years, knowing that it took the probabilistic bent, and as result, the physicists who gave it its first germs found themselves in disagreement with their own points of view. On the one hand, Bohr and with him the Copenhagen point of view and Einstein with EPR point of view, which where at the heart of a debate that took the form of controversy that only erupted with the death of one of the protagonist, Einstein which is the first to have imagined the entanglement property.

The road of quantum entanglement: from Einstein to 2022 Nobel Prize in Physics

Yu Shi

We explain the achievements that were awarded 2022 Nobel Prize in Physics, as well as the preceding and the later developments. The main notions and historic cornerstones of Bell inequalities, the related researches on quantum entanglement are reviewed, and the key physical ideas are emphasized. Among the early work, C. S. Wu's contributions using polarization-entangled photons from electron-positron annihilation are introduced.

Quantum mechanics and consciousness

F. Beck, Technische Hochschule Darmstadt

The first issue of JCS published an interview with Roger Penrose on his recent book Shadows of the Mind: A Search for the Missing Science of Consciousness (Clark, 1994). In it Professor Penrose, among other subjects, presented his views on the role of quantum mechanics on our way towards a better understanding of brain functioning and its relation to consciousness. In this note we comment on some aspects of his reasoning.

Quantum physics and conscious thought: Roger Penrose

Basil J. Hiley, F. David Peat

There can be few physicists who have delved as deeply into the philosophical implications of their subject as has David Bohm. It is therefore with some trepidation that I am paying my respects to him on the occasion of his retirement with an attempt of my own to relate questions of philosophy to those of the foundations of physics. The viewpoint that I am putting forward here attempts to relate questions that have been two of Bohm's major interests over the years; namely, a possible breakdown of quantum mechanics on a macroscopic scale and the physical basis of conscious thought. It must be evident to the reader that in both these topics I am venturing into dangerously speculative territory. Moreover others more expert that I (such as Wigner 1, as well as Bohm 2 himself) have put forward strongly-reasoned views which relate these topics. Yet I do feel that my own viewpoint is both well worth describing and sufficiently different from these others that the reader may find something of value here. But my account must necessarily be somewhat truncated, for reasons of space and of time. It is my intention to expand these thoughts at much greater length elsewhere.
