Reaching the ultimate energy resolution of a quantum detector

Reaching the ultimate energy resolution of a quantum detector

Quantum calorimeters can provide time-resolved measurement of single photons by converting them to detectable temperature changes. Here the authors demonstrate a calorimeter that reaches the lower bound of temperature resolution, determined by the coupling to its heat bath and associated fluctuation...
