TL;DR: Entanglement-based QKD is demonstrated between two ground stations separated by 1,120 kilometres at a finite secret-key rate of 0.12 bits per second, without the need for trusted relays, which increases the secure distance on the ground tenfold but also increases the practical security of QKKD to an unprecedented level.
Journal ArticleDOI
The electronic structure and spectral properties of ZnO and its defects
TL;DR: In this paper, the electronic structure of ZnO and its defects, which include intrinsic point defects and their complexes, have been calculated using full-potential linear Muffin-tin orbital method.
Journal ArticleDOI
Finite-key analysis for measurement-device-independent quantum key distribution
TL;DR: This work provides a rigorous security proof against general attacks in the finite-key regime by applying large deviation theory, specifically the Chernoff bound, to perform parameter estimation and demonstrates the feasibility of long-distance implementations of measurement-device-independent quantum key distribution within a reasonable time frame of signal transmission.
Journal ArticleDOI
Experimental demonstration of polarization encoding measurement-device-independent quantum key distribution.
TL;DR: This work paves the way for the realization of a MDI-QKD network, in which the users only need compact and low-cost state-preparation devices and can share complicated and expensive detectors provided by an untrusted network server.
