In everyday life, measuring temperature is pretty straightforward. But in the quantum world, which deals with the super small and the ultra-cold, determining how hot or cold something is starts to get more challenging. Now researchers have described a quantum process that uses a single atom as a thermometer to sensitively measure the temperature of an ultra-cold gas.
