报告摘要:
Device-independent quantum key distribution (DIQKD) is the art of using untrusted devices to distribute secret keys in an insecure network. It thus represents the ultimate form of cryptography, offering not only information-theoretic security against channel attacks, but also against attacks exploiting implementation loopholes. Practical DIQKD setups demand to distribute high quality entanglement and to perform low loss high accuracy measurements. This makes the realization of DIQKD extremely challenging and an outstanding milestone of quantum technology. In the last year, three experiments that demonstrate the central technological aspects needed for DIQKD where published. In this talk I will report on recent advances in theory and experiment that enabled these first proofs of concept.
