Establishing secure communication links at a global scale is a major potential application of
quantum information science but also extremely challenging for the underlying technology …

Global quantum communications will enable long-distance secure data transfer, networked
distributed quantum information processing, and other entanglement-enabled technologies …

Quantum key distribution (QKD) is a pioneering quantum technology on the brink of
widespread deployment. Nevertheless, the distribution of secret keys beyond a few 100 km …

Quantum key distribution (QKD) has the potential to improve communications security by
offering cryptographic keys whose security relies on the fundamental properties of quantum …

The security of real-world quantum key distribution (QKD) critically depends on the number
of data points the system can collect in a finite time interval. To date, state-of-the-art finite-key …

Quantum key distribution (QKD) provides the only intrinsically unconditional secure method
for communication based on the principle of quantum mechanics. Compared with fibre …

Satellite quantum communications are emerging within the panorama of quantum
technologies as a more effective strategy to distribute completely secure keys at very long …

In the postprocessing of quantum key distribution, the raw key bits from the mismatched-
basis measurements, where two parties use different bases, are normally discarded. Here …

The goal of this paper is to extend the framework of finite-size analysis recently developed
for quantum key distribution to continuous-variable protocols. We do not solve this problem …

Continuous-variable quantum key distribution (CV QKD) protocols with discrete modulation
are interesting due to their experimental simplicity and their great potential for massive …
