Quantum physics is extremely successful in describing nature, but it has many counter-intuitive features. In textbooks, quantum theory is often defined by a set of mathematical axioms. What is the physical intuition behind them? This is the first in a series of three videos exploring the axioms that define quantum physics.

In this video, part I, we review how quantum theory differs from classical theory in the way it describes physical systems. We join a class taught by Professor Valerio Scarani.

In the next two videos, we’ll go inside the minds of his students as they study the definition of quantum theory in the framework of “General probabilistic theories” and “no-signaling theories”.
