Device-independent quantum key distribution with random key basis
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 …

Optimized entropic uncertainty relations for multiple measurements
BF **e, F Ming, D Wang, L Ye, JL Chen - Physical Review A, 2021 - APS
Recently, an entropic uncertainty relation for multiple measurements was proposed by Liu et
al.[Phys. Rev. A 91, 042133 (2015) 10.1103/PhysRevA. 91.042133]. However, the lower …
