Conway–Kochen and the Finite Precision Loophole

Cecilia Flori

This is a revision of my original posting, in which I raised objections to part of the Conway-Kochen argument. I now agree with them that their recent reply answers my original concerns. In the first part of these notes (identical to the original), I give a reformulation of the part of the Conway-Kochen result that closes the contextuality loophole in the original Kochen-Specker (KS) theorem. In the second part (modified in this revision) I review my concerns connected with the finite time needed to make a measurement, and briefly indicate how Conway and Kochen have reponded to them.

This essay provides an analysis of two important theorems that arise in the context of quantum mechanics: the Kochen-Specker theorem, which challenges the existence of hidden variable theories; and the Conway-Kochen (free will) theorem, which can be seen as an improvement over the Kochen-Specker theorem, but instead focuses on challenging determinism.

A physicists' explanation of why thou shalt not clone one bit gives a stronger version of Conway and Kochen's theorem.
