World’s ‘most precise’ quantum thermometer designed

An article published today in Physical Review Letters reports the latest invention of the Researchers from the UAB and the University of Nottingham: the most precise quantum thermometer made up of just a handful of atoms and with the capacity to detect even the minutest differences in body temperature.

Combining thermodynamic tools with quantum metrology, researchers produced a quantum thermometer which is capable of measuring even the “smallest possible fluctuations” in temperature.

The researchers tried to sacrifice some accuracy to achieve “constant sensitivity over a wide range of temperatures.”  They also considered the maximum accuracy that may be possibly achieved in real-life situations wherein the time available for measuring temperatures may be limited.
