The Wigner's friend experiment is a thought experiment in which a so-called superobserver (Wigner) observes another observer (the friend) who has performed a quantum measurement on a physical system. In this setup Wigner treats the friend, the system

The famous Wigner’s friend experiment considers an observer—the friend—and a superobserver—Wigner—who treats the friend as a quantum system and her interaction with other quantum systems as unitary dynamics. This is at odds with the friend

Wigner’s friend is a thought experiment in theoretical quantum physics that challenges our understanding of quantum theory. The authors present a no-go theorem constraining the structure of probabilities in such a thought experiment and analyze the

One of the most fundamental open problems in physics is the unification of general relativity and quantum theory to a theory of quantum gravity. An aspect that might become relevant in such a theory is that the dynamical nature of causal structure pr

The quantum measurement problem can be regarded as the tension between the two alternative dynamics prescribed by quantum mechanics: the unitary evolution of the wave function and the state-update rule (or "collapse") at the instant a measurement tak

One of the reasons for the heated debates around the interpretations of quantum theory is a simple confusion between the notions of formalism $\textit{versus}$ interpretation. In this note, we make a clear distinction between them and show that there

The notorious Wigner's friend thought experiment (and modifications thereof) has in recent years received renewed interest especially due to new arguments that force us to question some of the fundamental assumptions of quantum theory. In this paper,

In a joint paper Jeff Bub and Itamar Pitowsky argued that the quantum state represents “the credence function of a rational agent […] who is updating probabilities on the basis of events that occur”. In the famous thought experiment designed by

The recently developed framework for quantum theory with no global causal order allows for quantum processes in which operations in local laboratories are neither causally ordered nor in a probabilistic mixture of definite causal orders. The causal r
