Quantum thermometer pushes the limits

Quantum thermometer pushes the limits

The researchers have studied the sensitivity of thermometers created with a handful of atoms, small enough to be capable of showing typical quantum-style behaviours.

The scientist have developed a quantum thermometer with enough precision to detect minute fluctuations in temperature in regions as small as the inside of a cell.

The researchers characterised the types of probes in detail, devices which could provide an estimation of the temperature with a never before seen precision. To do so, they combined thermodynamic tools with quantum metrology, which deals with ultra-precise measures in quantum systems.

The physicists searched to find the maximum precision which could be achieved in a real situation, in which measuring time could be very brief given unavoidable experimental limitations. In the research, they also observed that the thermometers could maintain a constant sensitivity in a wide range of temperatures by sacrificing some of their precision.
