Without Niels Bohr, QBism would be nothing. However in this talk, I try my best to explain how QBism is no minor tweak to Bohr's view on quantum mechanics. Along the way, I introduce three tenets of QBism: 1) All probabilities, including all quantum probabilities, are so subjective they never tell nature what to do. This includes probability-1 assignments. Quantum states thus have no...
From the early days of quantum mechanics, leading physicists were concerned about the role played by probabilities, the discontinuous nature of quantum jumps and the collapse of the state of quantum systems subject to measurement. While the evolution of a single localized quantum system already raises the most fundamental questions about the meaning of the theory, correlation measurements on...
In the quantum Bayesian formulation of quantum mechanics (QBism), the notion of an agent plays a central role. It is however a primitive notion that remains unresolved within the theory. If one entertains the possibility of automated quantum experiments designed and run by artificial intelligence, the problem of artificial agency gets into the focus. In the talk I will discuss the role and...
The title of this conference, "quantum limits of knowledge", expresses the common view that quantum mechanics imposes restrictions on the knowledge we can have about a physical system. QBism challenges this view by taking quantum states to represent states of belief rather than states of knowledge. This talk explains how this shift in language allows QBists to view the Born rule as an addition...
