China’s Quantum Satellite Security Has Been Broken

Next Big Future  August 22, 2019 Although quantum key distribution (QKD) security can theoretically be unbreakable, the actual implementations are not perfect and have been broken. In a spree of publications thereafter, an international team of researchers (Norway, Germany) has now demonstrated several methods to successfully eavesdrop on commercial QKD systems based on weaknesses of avalanche photodiodes operating in gated mode. This has sparked research on new approaches to securing communications networks…read more. Open Access TECHNICAL ARTICLE
