On Friday, researchers from the UAB and University of Nottingham announced of designing the smallest and most accurate quantum thermometer.

The thermometer is made up of atoms. It is so precise that it can detect the smallest fluctuations even in the microscopic regions. In the US Journal Physical Review Letter, the researchers have shared that the device is so small that it can display different ‘quantum’ features.

“Devising sensitive and practical nano-scale thermometers would represent a huge leap forward as such technology would enable a plethora of applications in bioscience, chemistry, physics and in the diagnosis and treatment of many diseases”, said researchers.

In order to design the thermometer, the researchers have taken the help of thermodynamic tools with quantum metrology.

Throughout their research, the scientists have observed few things, including whether or not the device is able to maintain a constant sensitivity on a range of temperatures even if it has to sacrifice some of the precision. They also studied the maximum accuracy that can be achieved in realistic situations.
