On the Gravitization of Quantum Mechanics 1: Quantum State Reduction
Open accessAbstract
This paper argues that the case for “gravitizing” quantum theory is at least as strong as that for quantizing gravity. Accordingly, the principles of general relativity must influence, and actually change , the very formalism of quantum mechanics. Most particularly, an “Einsteinian”, rather than a “Newtonian” treatment of the gravitational field should be adopted, in a quantum system, in order that the principle of equivalence be fully respected. This leads to an expectation that quantum superpositions of states involving a significant mass displacement should have a finite lifetime, in accordance with a proposal previously put forward by Diósi and the author.

Penrose postulates that quantum information is routinely lost in the quantum measurement process.
“To complete the picture it should be mentioned that Penrose postulates that (quantum) information is actually routinely lost in the quantum measurement process.”

The scenario leads to empirical predictions qualitatively equivalent to those involving objective information loss.
“Interestingly, such a scenario leads to empirical predictions, which are qualitatively equivalent to the ones involving objective information loss [49,50].”

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
