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

It can be difficult to understand quantum mechanics. That's okay, because, in the early days of the Internet, few could understand how that worked. Now, new developments in quantum communication may ...

Our successful long-range signal reception with a Rydberg sensor represents a significant milestone for the technology and the advent of Rydberg atomic radio.” — David A. Anderson, Ph.D., CEO of ...

The world’s longest quantum communications link has been set up between China and South Africa, spanning a record-breaking 12,900 km (8,015 miles). The connection takes advantage of quantum physics ...

In June 2025, Quantum Computing Inc. QUBT achieved a pivotal milestone with the shipment of its first commercial entangled photon source. This marked the company’s formal entry into the emerging ...

For years, scientists have imagined a future where secure quantum links circle the planet from space. Satellites would create pairs of entangled photons and send them down to distant stations on Earth ...

Panaji: One of the biggest challenges in the present day’s communication systems is the risk of interception and hacking, and India is steadily moving.

Researchers recently connected their campuses with an experimental quantum communications network using two optical fibers. Researchers at the University of Rochester and Rochester Institute of ...

The Defense Advanced Research Projects Agency is angling to lay the groundwork for a computational network that can integrate both traditional and quantum-powered systems ahead of further ...

Quantum key distribution (QKD) exploits the intrinsic properties of quantum mechanics to enable the secure exchange of cryptographic keys between distant parties. By utilising quantum states of light, ...

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 ...
