Secure quantum key distribution (QKD) is limited by the Earth's horizon, weather, and
turbulence in the atmosphere. We will outline the analysis, design, and early stages of our …

Free-space quantum key distribution (QKD) systems are often designed to implement
polarization-encoding protocols. Alternatively, time-bin/phase-encoding protocols are …

Next generation communications will require the exploration of alternatives to existing
technologies to enable end-to-end connections for secure data exchange. 5G presents …

The security of sensitive information exchange has become a major topic in recent years.
Quantum Key Distribution (QKD) provides a highly secure approach to share random …

In recent years, quantum key distribution (QKD) has seen the first proof-of-concept
demonstrations from space. Next on the agenda towards a full-blown global quantum …

Quantum Key Distribution (QKD), a technology for growing mathematically secure key
encryption keys, is now on the verge of becoming widely commercially available. Due to lack …

Measurement-device-independent quantum key distribution (MDI-QKD) has demonstrated
significant security in countering detection-side attacks, expanding the practical applications …

We analyze the turbulence affects on a quantum-key distribution (QKD) system and
demonstrate them experimentally. We demonstrate a QKD scheme, in which we transform …

Terrestrial free-space (FS) quantum key distribution (QKD) is ideally suited for deployment in
dense urban environments. The transition from laboratory to commercial deployment …

Free-space quantum key distribution (QKD) based on mobile platforms, such as satellites,
drones, and vehicles, is considered a promising way to overcome the rate-distance limit …
