#UAB researchers design the most precise quantum thermometer to date: The device would be capable of measuring the temperature of a cell's interior Researchers from the UAB and the University of Nottingham, in an article published today in Physical Review Letters, have fixed the limits of thermometry, i e.,, they have established the smallest possible fluctuation in temperature which can be measured. 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. UAB researchers design the most precise quantum thermometer to date: The device would be capable of measuring the temperature of a cell's interior The researchers characterised these 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 given very brief unavoidable experimental limitations. In the research, they also observed that these thermometers could maintain a constant sensitivity in a wide range of temperatures by sacrificing some of their precision. For the authors of the research"finding a nanothermometer sensitive enough at this scale is a great step forward in the field of nanotechnology, with applications in biology, chemistry, physics and even in the diagnosis and treatment of diseases
