 QBists maintain that rather than (either directly or indirectly) representing a physical system, a quantum state represents the epistemic state of the one who assigns it concerning that agent’s possible future experiences. It does this by specifying the agent’s coherent degree of belief (credence) in each of a variety of alternative experiences that may result from a specific act the agent may perform. To get an idea of the kinds of experience and act the QBist has in mind it is helpful to think of the possible outcomes of a quantum measurement on a physical system. But QBists have proposed the extension of the view to encompass every experience that may result from any action (Fuchs, Mermin, and Schack 2014; Mermin 2017).
