Relative Facts of Relational Quantum Mechanics are Incompatible with Quantum Mechanics

چکیده
Relational Quantum Mechanics (RQM) claims to be an interpretation of quantum theory [see arXiv:2109.09170, which appears in the Oxford Handbook History Interpretation Physics]. However, there are significant departures from theory: (i) RQM measurement outcomes arise interactions entangle a system $S$ and observer $A$ without decoherence, (ii) such outcome is "fact" relative $A$, but it not fact another $B$ who has interacted with or during foregoing process. For $S \otimes A$ remains entangled. We derive GHZ-like contradiction showing that facts described by these statements incompatible theory. Hence should considered theory, according criterion for interpretations we have introduced. The states whenever introduces notion outcomes, whatever they are, must follow probability distribution specified Born rule.

Relational Quantum Mechanics
In this internship report, we present Carlo Rovelli’s relational interpretation of quantum mechanics, focusing on its historical and conceptual roots. A critical analysis of the Einstein-Podolsky-Rosen argument is then put forward, which suggests that the phenomenon of ‘quantum non-locality’ is an artifact of the orthodox interpretation, and not a physical effect. A speculative discussion of th...
متن کاملQuantum Mechanics and the Mechanism of Sexual Reproduction
There are many claims that quantum mechanics plays a key role in the origin and/or operation of biological organisms. The mechanism of the meiosis, mitosis and gametes life cycle from the view-point of quantum for human has been represented. The quantum gates have been used to simulate these processes for the first time. The reason of several hundred sperms has been explained in the male too

متن کاملSmallest Relational Mechanics Model of Quantum Cosmology
Relational particle mechanics are models in which there is, overall, no time, position, orientation (nor, sometimes, scale). They are useful for whole-universe modelling the setting for quantum cosmology. This note concerns 3 particles in 1d in shape-scale split variables. The scale part parallels certain Friedmann equations, while in this note the shape part involves functions on the circle. T...
