No qualms about quantum theory

Professor Berge Englert from Centre for Quantum Technologies (Singapore)

Quantum theory has been singularly successful in the almost one-hundred years since its foundations were laid by Albert Einstein, Niels Bohr, Werner Heisenberg, Erwin Schrödinger, Max Born, Paul Dirac, and others. Nevertheless, there is a debate – seemingly never ending – about the so-called “measurement problem” and other perceived problems. I shall argue that quantum theory is a well-defined local theory with a clear interpretation. No measurement problem or any other foundational matters are waiting to be settled. The answers to questions such as: What is a physical theory? What are the preexisting concepts in quantum theory? Probabilities in quantum theory are probabilities for what? What is state reduction? Do wave functions collapse? Is there instant action at a distant? Is quantum theory nonlocal? Where is Heisenberg’s cut? How many interpretations do we need? Is there a measurement problem? demonstrate the case.
