# Understanding the Frauchiger–Renner Argument

@article{Bub2020UnderstandingTF, title={Understanding the Frauchiger–Renner Argument}, author={Jeffrey Bub}, journal={arXiv: Quantum Physics}, year={2020} }

In 2018, Daniela Frauchiger and Renato Renner published an article in Nature Communications entitled `Quantum theory cannot consistently describe the use of itself.' I clarify the significance of the result and point out a common and persistent misunderstanding of the argument, which has been attacked as flawed from a variety of interpretational perspectives.

### Comment on "Understanding the Frauchiger-Renner argument" by Jeffrey Bub

- Philosophy
- 2020

Bub has recently claimed that the Frauchiger-Renner argument does not require an assumption that the state vector undergoes projection after measurement. It is shown that this claim is not true, and…

### The Quantum Rashomon Effect: A Strengthened Frauchiger-Renner Argument

- Physics
- 2020

A state-independent Frauchiger-Renner scenario is exhibited, eliminating any necessity for entanglement and ensuring that the quantum Rashomon effect is thus a generic feature of the quantum world.

### Quantum erasing the memory of Wigner's friend

- PhysicsQuantum
- 2021

It is argued that the three apparently incompatible properties used to question the consistency of quantum mechanics correspond to two logically distinct contexts: either assuming that Wigner has full control over his friends' lab, or conversely that some part of the labs remain unaffected byWigner's subsequent measurements.

### On the paper"Quantum theory cannot consistently describe the use of itself"

- Philosophy

In the paper “Quantum theory cannot consistently describe the use of itself” by D. Frauchiger and R. Renner an atempt is made at proving a “no-go theorem” that states that either quantum theory…

### Testing quantum theory with thought experiments

- Physics, Education

Quantum mechanics is one of our most successful physical theories; its predictions agree with experimental observations to an extremely high accuracy. However, the bare formalism of quantum theory…

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

- Physics
- 2021

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…

### The Open Systems View

- Philosophy
- 2021

There is a deeply entrenched view in philosophy and physics, the closed systems view, according to which isolated systems are conceived of as fundamental. On this view, when a system is under the…

### Local Quantum Reality

- Physics
- 2020

Unperformed measurements have no results. Unobserved results can affect future measurements.

### Agents governed by quantum mechanics can use it intersubjectively and consistently

- Physics
- 2020

A simple operational principle called superpositional solipsism is proposed to aid rational agents in making situational inferences and it is shown that the principle leads to sound inferences in all operationally-relevant instances.

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.

Bell's theorem is demonstrated, without using inequalities, for an experiment with two particles, and it is shown that, if realism and Lorentz-invariant observables are assumed, it can derive a contradiction with quantum mechanics.
