It is challenged only recently that the precision attainable in any measurement of a physical parameter is fundamentally limited by the quantum Cramer-Rao Bound (QCRB). Here, targeting at measuring parameters in strongly dissipative systems, we propose an innovative measurement scheme called {\it dissipative adiabatic measurement} and theoretically show that it can beat the QCRB. Unlike projective measurements, our measurement scheme, though consuming more time, does not collapse the measured…

We study the Bayesian approach to thermometry with no prior knowledge about the expected temperature scale, through the example of energy measurements on fully or partially thermalized qubit probes.
Surpassing the thermal Cramér-Rao bound with collisional thermometry
• Physics
• 2020
In collisional thermometry, a system in contact with the thermal bath is probed by a stream of ancillas. Coherences and collective measurements were shown to improve the Fisher information in some

This work shows through a minimal qubit model that individual ancillas can already outperform the thermal Cramer-Rao bound, and sets forth the notion of metrology in a sequential interactions setting, and may inspire further advances in quantum thermometry.

A novel minimally disturbing method for sub-nK thermometry in a Bose-Einstein condensate (BEC) based on the Bose polaron model, which can compete with state-of-the-art destructive techniques, even when the estimates are built from the outcomes of accessible (suboptimal) quadrature measurements.
