Exploring Locality in Physics

Welcome to Episode 1 of my new Quantum Foundations podcast! I interview Dr Nicetu Tibau Vidal, a Research Fellow at the University of Hong Kong. We discuss locality in quantum physics, informed by Nicetu's PhD research at the University of Oxford and his ongoing work.

It is often stated that "if two particles are quantum entangled, doing something to one instantly influences a distant entangled particle." This statement is backed by Bell's Theorem, said to require sacrificing locality (distant particles can't instantly influence each other) or realism (our theories describe real aspects of the universe). In this podcast, Dr. Nicetu Tibau Vidal explains a third option: we can keep both locality and realism within standard quantum mechanics. However, we need to update our understanding of the physical properties of a particle that really exist — with important implications for the nature of reality.
