This work addresses a foundational issue in quantum cryptography, revealing a critical flaw in security proofs that impacts researchers and practitioners relying on QKD for secure communication.
The paper presents a counter-example challenging the common interpretation of the trace distance criterion as a failure probability in quantum key distribution (QKD) protocols, highlighting that this undermines the claimed security proofs for QKD keys.
A simple counter-example is given on the prevalent interpretation of the trace distance criterion as failure probability in quantum key distribution protocols. A summary of its ramifications is listed.
