From spectral structure to sensing limits in quantum thermometry
Youssef Aiache, Simone Cavazzoni, Abderrahim El Allati +2
The precision of a quantum thermometer is fundamentally constrained by the spectral structure of the probe itself, and a systematic mapping between the configurations of energy lev…

Nonequilibrium quantum thermometry with noncommutative system-bath couplings
Youssef Aiache, Abderrahim El Allati, Ä°lkay Demir +1
Accurate temperature estimation in the quantum and cryogenic regimes remains a fundamental challenge. Here, we investigate nonequilibrium quantum thermometry using a single-qubit p…
