Introduction to QBism Seminar

QBism is an approach to quantum theory which is grounded in the personalist conception of probability pioneered by Ramsey, de Finetti and Savage. According to QBism, a quantum state represents an agent's personal degrees of belief regarding the consequences of her actions on her external world. The quantum formalism provides consistency criteria that enable the agent to make better decisions. This talk gives an introduction to QBism and addresses, among other things, these questions: What is a measurement? What does QBism have to say about the EPR criterion of reality? Why don't the recent no-go theorems for epistemic interpretations of quantum states apply to QBism? Jointly, the answers to these questions provide clues to the character of the physical world.
