Book, "The Quantum Measurement Problem" by Michael Steiner and Ronald Rendell

From review by Peter Bussey, Contemporary Physics:

"...Steiner and Rendell present a detailed mathematical argument that the Schrödinger equation on its own cannot normally lead to an outcome that resembles a random measurement event...its conclusion is quite important since some eminent physicists, such as Feynman, seem to have believed otherwise...The most important chapter of the book is devoted to a thorough and extensive survey of all the approaches to the measurement problem...These are all presented, discussed and evaluated in a very extensive collection that is more complete than in many other works on the subject...The historical discussion is very readable and informative in its own right, and of great value to have. It includes quite a lot of material that I had not encountered before…This book is idiosyncratic but full of information, and its treatment of the quantum physics is in my opinion comprehensive, sound and reasonable...It is a book, then, that will be helpful to open-minded experts in the field, on the whole, and for those who seek to embark on further research in this area."

About Me

Ronald Rendell

Senior Scientist

Dr. Rendell received a Ph.D. in theoretical physics (1980) from the University of California, Santa Barbara. Dr. Rendell has performed basic theoretical research in a variety of areas with over 80 publications in archival journals. These include significant contributions to relaxations and transport in complex material systems, transport in electronic materials, plasmonics in nanostructures and metamaterials, quantum information, quantum decoherence and entanglement, and quantum measurement. In his Ph.D. work, Dr. Rendell originated the concept of the localized surface plasmon and identified the first experimental observation of these excitations. He later developed theory and modeling of plasmo-photonic nanostructured arrays and protein-based plasmonic nanostructures. Dr. Rendell developed theory and modeling on relaxation in complex material systems (such as polymers, glasses, electronic materials, dielectrics, ionic conductors) which exhibit time-dependent phenomena related to many-body correlations in the materials. He first identified diffusion in the phase space of relaxing chaotic Hamiltonians as the origin of such time-dependences as successfully described by Ngai’s coupling model of relaxation. Dr. Rendell developed theory in the area of quantum information and entanglement and worked on research projects involving qubits in semiconductor quantum dots, integrated atom optics, and atomic slow light devices. His current research is in the area of foundations of quantum mechanics, specifically on the quantum measurement problem. During 2005-2006, Dr. Rendell was a member of Prof. Yakir Aharonov's Center for Quantum Studies where he conducted fundamental quantum mechanics research. In 2006 Dr. Rendell was a founding member of Inspire Institute, and is currently on the board of directors. In 2018, Dr. Rendell coauthored with Dr. Michael Steiner the book “The Quantum Measurement Problem”, published by Inspire Institute, Inc.

To the extent there is entanglement, there is no measurement.
