I interview Dr Andrea Di Biagio, who is a postdoctoral research fellow at IQOQI Vienna. We discuss Andrea's journey through interpretations of quantum theory, including QBism, Relational Quantum Mechanics, Everettian Quantum Theory and Wigner's friend. These topics have been subjects of Andrea's past and active research, including work with Prof. Carlo Rovelli.

Dr. Sam Kuypers, a postdoctoral research fellow at the Université de Montréal, delves into the intriguing many-worlds interpretation of quantum mechanics. He discusses how this theory redefines measurement and observation, leading to branching realities. With insights into energy conservation and personal identity across multiple worlds, Sam also addresses philosophical dilemmas posed by quantum probabilities. The conversation takes a light-hearted turn when he relates complex quantum ideas to everyday moments, making the concepts both accessible and entertaining!

In this enlightening discussion, Dr. Nick Ormrod, a post-doctoral research fellow at the Perimeter Institute, dives deep into his groundbreaking interpretation of quantum theory, where reality emerges from causal structures. He explores how causation reshapes our understanding of the universe, challenging traditional deterministic views. Nick also critiques the Copenhagen interpretation and bridges classical and quantum mechanics by discussing joint probabilities and the measurement problem. This thought-provoking conversation redefines the fabric of reality and inspires new avenues for scientific inquiry.

Dr. Nicetu Tibau Vidal, a Research Fellow at the University of Hong Kong and former Oxford PhD student, discusses the intriguing interplay of locality and quantum physics. He explores the validity of local realism, challenging the idea that entangled particles' actions are non-local. The conversation unpacks Bell's theorem and its implications, alongside insightful thought experiments like sock measurements. Nicetu also delves into how our understanding of particles and their properties needs to evolve, with profound implications for the nature of reality.
