Can Quantum Key Distribution Be Secure

Abstract

The importance of quantum key distribution as a cryptographic method depends upon its purported strong security guarantee. The following gives reasons on why such strong security guarantee has not been validly established and why good QKD security is difficult to obtain.

This new version is a rewriting of the last v1 for a broader group of readers. It also contains a new specific counter-example not in v1
