Quantum key distribution (QKD) constitutes a symmetric secret key negotiation protocol
capable of maintaining information-theoretic security. Given the recent advances in QKD …

Concerted efforts are underway to establish an infrastructure for a global quantum Internet to
realise a spectrum of quantum technologies. This will enable more precise sensors, secure …

Quantum key distribution (QKD) is a family of protocols for growing a private encryption key
between two parties. Despite much progress, all ground-based QKD approaches have a …

Satellite-based quantum terminals are a feasible way to extend the reach of quantum
communication protocols such as quantum key distribution (QKD) to the global scale. To that …

We present a ground-to-space quantum key distribution (QKD) mission concept and the
accompanying feasibility study for the development of the associated low earth orbit …

Quantum key distribution (QKD) has matured in recent years from laboratory proof-of-
principle demonstrations to commercially available systems. One of the major bottlenecks is …

Satellites are the most efficient way to achieve global scale quantum communication (Q.
Com) because unavoidable losses restrict fiber based Q. Com to a few hundred kilometers …

Abstract Models of quantum systems on curved space-times lack sufficient experimental
verification. Some speculative theories suggest that quantum correlations, such as …

Quantum key distribution (QKD) uses the fundamental principles of quantum mechanics to
share unconditionally secure keys between distant users. Previous works based on the …

Single-photon detectors (SPDs) play important roles in highly sensitive detection
applications, such as fluorescence spectroscopy, remote sensing and ranging, deep space …
