Scientists are learning to engineer light in rich, multidimensional ways that dramatically increase how much information a ...

Physicists have developed a breakthrough concept in quantum encryption that makes private communication more secure over significantly longer distances, surpassing state-of-the-art technologies. For ...

In this era of instant communication and rising cyber attacks, keeping things secret has never been harder. Quantum computers will make it even harder once they arrive, when someday they will be able ...

Photon purity is more than a technical detail. In photonic quantum computing, orderly single-photon streams are easier to control, synchronize, and scale. They also reduce the risk of errors and ...

If quantum communication becomes mainstream, our entire approach to digital security could change.

A major breakthrough in quantum technology was achieved in October 2024: the first-ever quantum satellite communication link between China and South Africa. The connection spanned a remarkable 12,900 ...

An interoperable Optical Ground Station will provide a long-distance Quantum Key Distribution link between Asia and Europe to scale next-generation cybersecurity and services SINGAPORE & ...

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 ...

Modern defence and communications systems, and much of our national infrastructure, are reliant on uninterrupted satellite ...

Located at Heriot-Watt University, it's the UK’s first facility dedicated to quantum key distribution - or QKD - via satellite. By creating virtually unhackable encryption keys, it aims to help ...

Quantum information, computation and communication form a rapidly evolving field where the counter‐intuitive principles of quantum mechanics are harnessed for processing and securely transmitting ...
