In the quest for ultra-secure, long-range quantum communication, two major challenges stand in the way: the unpredictable nature of atmospheric turbulence and the limitations of current optical ...

The German consortium QuINSiDa has achieved a major step toward mobile quantum-secure communication. They demonstrated a one-of-a-kind free-space data transfer channel supporting, for the first time, ...

A University of Ottawa team has developed a new way to protect free-space quantum key distribution (QKD) from atmospheric turbulence, one of the main causes of distortion and errors when sending ...

This Collection supports and amplifies research related to SDG 9 - Industry, Innovation and Infrastructure. The ability to control the phase, polarization, and intensity of light is extensively ...

Researchers have built a new platform that produces ultrashort UV-C laser pulses and detects them at room temperature using atom-thin materials. The light flashes last just femtoseconds and can be ...

The advent of the fifth-generation (5G) technology has revolutionized the way we think about communication networks, enabling a plethora of new use cases and scenarios that were not possible with ...
