Are there unsolved problems in the interpretation of quantum mechanics?

Christopher Giguere

Many open questions or unsolved problems exist in all areas of physics. In Foundations of Physics, one open question, a century old, is how does quantum reality give rise to classical reality. This is called the quantum-classical transition, for which there are many interpretations formally called the interpretations of quantum mechanics. Now, the open problem may be located in physics, but is ultimately a philosophical problem. Physics has been unable to solve this problem with the methods of physics, say mathematics. Instead, the problem is philosophical in nature—the discipline from which physics came about—and so needs (in spite of what many hardcore physicists may detest) philosophy to solve this problem. A new angle on the subject is required; perhaps a different science may be useful, that of neuroscience. The alternative theory presented here, the Brain Interpretation of Quantum Mechanics (BIQM)—which states that classical reality is the brain’s interpretation of quantum reality appearing in our collective consciousness—represents a multidisciplinary fusion of philosophy of physics, neuroscience, and consciousness studies to attack this key and lingering unsolved problem in the Foundations of Physics. This paper seeks to provide solutions for two main unsolved problems: 1) the interpretation of quantum mechanics and, by virtue, 2) the consciousness/matter problem, which is an open problem in the philosophy of mind and consciousness studies. This article not only represents an interpretation of quantum mechanics, but is a fairly comprehensive theory of reality.

Although it is 70 years old, there are still areas of quantum theory which are open to interpretation. This book deals with such interpretational problems, and in particular with the issue of the measurement process. The main theme is whether quantum mechanics can be viewed as a (semantically) complete theory, namely as a theory capable of describing not only the physical object under observation but also the measuring instruments used to detect the properties of that physical object. The problematic aspects arise from the fact that the measuring instruments themselves behave as classical physical systems. Thus, we are faced with the open problem of the transition from the quantum to the classical, or more explicitly, the problem of why the composition of many quantum micro-objects gives rise to classical macro-objects. This book goes carefully, exhaustively, and deeply into the interpretational problems of quantum mechanics induced by the measurement process. The solution of many relevant issues, as well as the problems that remain unsolved, emerge clearly. The discussion itself is self-contained and the technical parts are reader-friendly. This book is of value to graduate students and researchers who have an interest in the physical, mathematical, and philosophical foundations of quantum mechanics.

Abstract Because the origin of the wave-particle duality of quantum mechanics has always been an unsolved problem in physics. Therefore, this article attempts to propose a feasible interpretation of the wave-particle duality origin of quantum mechanics in order to eliminate the confusion of probability waves in quantum mechanics.
