On Conway and Kochen's "Thou shalt not clone one bit!"

TL;DR

This paper provides a physicist's explanation for why cloning a single quantum bit is fundamentally impossible, strengthening Conway and Kochen's theorem with a more robust argument.

Contribution

It offers a new, stronger version of Conway and Kochen's theorem by providing a physicist's perspective on the impossibility of cloning one quantum bit.

Findings

Cloning one quantum bit is fundamentally impossible.

A stronger theorem than Conway and Kochen's original is established.

The explanation enhances understanding of quantum no-cloning principles.

Abstract

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