The Most Precise Quantum Thermometer Ever

Saturday, June 6, 2015 - 12:40 in Physics & Chemistry

Physics at the UAB have found the “formula” to construct a quantum thermometer with enough precision to detect minute fluctuations in temperature in regions as small as the inside of a cell. The research appears today in the journal Physical Review Letters.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. read more
