Quantum No-Cloning Theorem Certified by Bell's Theorem

TL;DR

This paper demonstrates that the quantum no-cloning theorem can be certified through Bell's theorem, highlighting the fundamental nonlocality of our physical world.

Contribution

It establishes a direct link between quantum no-cloning and Bell's theorem, providing a new way to certify no-cloning via Bell inequalities.

Findings

Quantum no-cloning can be certified by Bell's theorem.

The connection reflects the nonlocal nature of quantum physics.

Bell's inequalities can serve as certificates for no-cloning.

Abstract

We investigate the connection between quantum no-cloning theorem and Bell's theorem. Designing some Bell's inequalities, we show that quantum no-cloning theorem can always be certified by Bell's theorem, and this fact in turn reflects that our physical world is essentially nonlocal.
