New atom-based thermometer measures temperature more accurately

Scientists have developed a new method for measuring temperature extremely accurately by using giant ‘Rydberg’ atoms. This atomic thermometer provides accurate measurements ‘out of the box,’ without needing initial factory adjustments, because it relies on the basic principles of quantum physics. By using Rydberg atoms’ sensitivity to environmental changes, this technique could simplify temperature sensing in extreme environments, from space to high-precision industries.
