Quantum Optics Jena's ELVIS System Completes First ISO/IEC 23837 Hardware Security Evaluation - Quantum Computing Report

German quantum communications developer Quantum Optics Jena GmbH (QOJ) has announced that its ELVIS quantum key distribution (QKD) system has completed an independent security evaluation under the ISO/IEC 23837 international standard. Conducted over a three-month testing period by independent cybersecurity assessment firm TÜV Informationstechnik GmbH (TÜVIT), the evaluation subjected the entanglement-based hardware platform to six targeted security assessments, discovering no major vulnerabilities or exploitable side-channel weaknesses. While QKD provides theoretical security grounded in the laws of quantum mechanics, commercial implementations remain vulnerable to hardware side-channel attacks. Adversaries frequently target physical hardware components—such as lasers, single-photon detectors, modulators, and optical splitters—rather than [...]
