Query: On quantum interferometric measurements of temperature   We provide a detailed description of the quantum interferometric thermometer,
which is a device that estimates the temperature of a sample from the
measurements of the optical phase. For the first time, we rigorously analyze
the operation of such a device by studying the interaction of the optical probe
system prepared in a single-mode Gaussian state with a heated sample modeled as
a dissipative thermal reservoir. We find that this approach to thermometry is
capable of measuring the temperature of a sample in the nanokelvin regime.
Furthermore, we compare the fundamental precision of quantum interferometric
thermometers with the theoretical precision offered by the classical idealized
pyrometers, which infer the temperature from a measurement of the total thermal
radiation emitted by the sample. We find that the interferometric thermometer
provides a superior performance in temperature sensing even when compared with
this idealized pyrometer. We predict that interferometric thermometers will
prove useful for ultraprecise temperature sensing and stabilization of quantum
optical experiments based on the nonlinear crystals and atomic vapors.
