Abstract algebra unlocks distinguishable states for quantum systems

Researchers around the world are racing to develop new quantum-based systems for sensing, communication, computing and control that have the promise of outperforming traditional systems. Creating stable, measurable, distinguishable ...

Using quantum entanglement to secure ground-to-satellite timing

From mobile phones and banking systems to aircraft, ships and emergency services, much of modern life relies on precise timing signals from satellites. Known as the Global Navigation Satellite System (GNSS), satellites carrying ...

Plug-and-play single-photon source can work at room temperature

The Korea Research Institute of Standards and Science (KRISS) has developed a room-temperature single-photon source built into a compact 19-inch rack-mounted device that operates without cryogenic cooling. Designed as a plug-and-play ...
