Abstract

Wave–particle duality is one of the defining features of quantum physics, describing the complementary wave-like and particle-like behavior of quantum systems. This talk explores how these complementary properties can be linked to security certification in semi-device-independent quantum communication. Using experimentally accessible interferometric quantities such as visibility and distinguishability, non-classicality and positive key rates can be certified in tunable interferometers. The presentation also includes a proof-of-principle experiment using orbital-angular-momentum states of light and extensions to higher-dimensional multipath interferometers.
