A theoretical framework for creating practical quantum thermometers that are optimized for taking the temperature of tiny structures as varied as living cells and quantum bits has been created by ...

Physicists have devised a thermometer that can potentially measure temperatures as low as tens of trillionths of a degree above absolute zero. As physicists strive to cool atoms down to ever more ...
