Abstract The Free Energy Principle (FEP) states that under suitable conditions of weak
coupling, random dynamical systems with sufficient degrees of freedom will behave so as to …

Recent years have seen significant advances in the study of symmetric informationally
complete (SIC) quantum measurements, also known as maximal sets of complex …

Although complex numbers are essential in mathematics, they are not needed to describe
physical experiments, as those are expressed in terms of probabilities, hence real numbers …

The second quantum revolution has been built on a foundation of fundamental research at
the intersection of physics and information science, giving rise to the discipline we now call …

Quantum theory provides an extremely accurate description of fundamental processes in
physics. It thus seems likely that the theory is applicable beyond the, mostly microscopic …

Quantum measurements play a fundamental role in quantum mechanics. Especially,
generalized quantum measurements provide a powerful and versatile tool to extract …

Quantum mechanics has irked physicists ever since its conception more than 100 years ago.
While some of the misgivings, such as it being unintuitive, are merely aesthetic, quantum …

Does quantum theory apply at all scales, including that of observers? New light on this
fundamental question has recently been shed through a resurgence of interest in the long …

We give an introduction to the QBist interpretation of quantum mechanics, which removes
the paradoxes, conundra, and pseudo-problems that have plagued quantum foundations for …
