In the initial stage of quantum Internet, most practical networks have been deployed relying on diverse individual key distribution (QKD) protocols. However, this single-protocol paradigm cannot fulfill heterogeneous requirements users, hence market-penetration is limited. Given recent advances in QKD protocols, next generation are expected to support both legacy and emerging evolution from mul...

Free-space angular-chirp-enhanced delay (FACED) is an ultrafast laser-scanning technique that allows for high imaging speed at the scale orders of magnitude greater than current technologies. However, this advantage has only been restricted to bright-field and fluorescence imaging—limiting variety image contents hindering its applicability in image-based bioassay, which increasingly demands ric...
