QKD offers a fundamentally different approach to securing communications, but cost, infrastructure and scalability challenges ...

This process is fundamental to quantum key distribution," Ding said. "Some years ago, we only dreamt of using quantum dots in real-world quantum communication scenarios. Today, we are thrilled to ...

As part of the QuNET project, researchers have demonstrated how quantum key distribution works reliably via hybrid and mobile channels. The results are milestones for sovereign, quantum-secured ...

Physicists have developed a spectral-filtering technique that strips away unwanted extra photons from quantum light sources, tackling one of the most persistent obstacles in quantum optics. The method ...

We have been under the assumption that the encryption that protects our bank accounts, patient records, and government ...

Defining security in quantum key distribution with Carla Ferradini, Martin Sandfuchs, and Renato Renner The security of quantum key distribution (QKD) is quantified by a parameter ε >0, which—under ...

In the race to secure digital infrastructure against the looming threat of quantum computing, space has emerged as an indispensable theater. Satellites, once primarily vehicles for reconnaissance and ...

Quantum computers are considered the next big thing in IT – at least for some areas like AI model training or in science and ...
