# A"thoughtful"Local Friendliness no-go theorem: a prospective experiment with new assumptions to suit

@inproceedings{Wiseman2022AthoughtfulLocalFN, title={A"thoughtful"Local Friendliness no-go theorem: a prospective experiment with new assumptions to suit}, author={Howard M. Wiseman and Eric G. Cavalcanti and Eleanor Gilbert Rieffel}, year={2022} }

A recent paper by two of us and co-workers [1], based on an extended Wigner’s friend scenario, demonstrated that certain empirical correlations predicted by quantum theory (QT) violate inequalities derived from a set of metaphysical assumptions we called “Local Friendliness” (LF). These assumptions are strictly weaker than those used for deriving Bell inequalities. Crucial to the theorem was the premise that a quantum system with reversible evolution could be an observer (colloquially, a…

It is suggested that cleaving to Leibniz’s principle requires extending relativity to events themselves, and this formulation of the Local Friendliness no-go theorem of Bong et al. is provided.

Spontaneous collapse models and Bohmian mechanics are two different solutions to the measurement problem plaguing orthodox quantum mechanics. They have, a priori nothing in common. At a formal level,…

- Philosophy

In a recent work, Bong et al. [Nature Physics 16, 1199 (2020)] proved a no-go theorem demon-strating a contradiction between a set of assumptions called “Local Friendliness” (LF) and certain quantum…

### A No-Go Theorem for Observer-Independent Facts

- PhysicsEntropy
- 2018

A no-go theorem for observer-independent facts, which would be common both for Wigner and the friend is derived and is analyzed in the context of a newly-derived theorem arXiv:1604.07422, where Frauchiger and Renner prove that “single-world interpretations of quantum theory cannot be self-consistent”.

### A strong no-go theorem on the Wigner’s friend paradox

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-standing Wigner’s…

### No-go theorem based on incomplete information of Wigner about his friend

- Physics

The notion of measurements is central for many debates in quantum mechanics. One critical point is whether a measurement can be regarded as an absolute event, giving the same result for any observer…

This result implies that quantum theory should be interpreted in an observer-dependent way, through recent no-go theorems that construct an extended Wigner’s friend scenario with four observers.
