A new high-speed, miniaturized chip-based device paves the way for scalable and secure random number generation for everyday devices to strengthen security without sacrificing speed.

Researchers at Tohoku University developed a photonic router that can direct single and entangled (quantum) photons at unprecedented levels of efficiency. This may bring us closer to realizing superfast quantum tech.

In a world-first, researchers from the Femtosecond Spectroscopy Unit at the Okinawa Institute of Science and Technology (OIST) have directly observed the evolution of the elusive dark excitons in atomically thin materials, laying the foundation for new breakthroughs in both classical and quantum information technologies. Their findings have been published in Nature Communications. Professor Keshav Dani, head of the unit, highlights the significance: "Dark excitons have great potential as information carriers, because they are inherently less likely to interact with light, and hence less prone to degradation of their quantum properties. However, this invisibility also makes them very challenging to study and manipulate. Building on a previous breakthrough at OIST in 2020, we have opened a route to the creation, observation, and manipulation of dark excitons."

Physicists in Australia and Britain have reshaped quantum uncertainty to sidestep the restriction imposed by the famous Heisenberg uncertainty principle – a result that could underpin future ultra-precise sensor technology used in navigation, medicine and astronomy.
