Recent arguments, involving entangled systems shared by sets of Wigner’s friend arrangements, allegedly show that the assumption that the experiments performed by the friends yield definite outcomes, is incompatible with quantum predictions. From this, it is concluded that the results of measurements cannot be thought of as being actual or objective. Here, I show that these arguments depend upon a mistaken assumption, regarding the correlations between the results of the friends and those of…

A No-Go Theorem for Observer-Independent Facts

- Computer Science, MedicineEntropy
- 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”.

Quantum theory cannot consistently describe the use of itself

A variant of Wigner’s friend Gedankenexperiment where each of the current interpretations of QM fails in giving a consistent description, indicating that quantum theory cannot be extrapolated to complex systems, at least not in a straightforward manner.

The measurement process is composed of premeasurement and an irreversible decoherence via interaction with an environment and the system ends up in a probabilistic mixture of the eigenstates of the measured observable.
