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…
Quantum metrology of a structured reservoir
Youssef Aiache, Asghar Ullah, Ãzgür E. MüstecaplıoÄlu +1
Accurately characterizing the properties of structured reservoirs is a key challenge in quantum systems and is of great importance for advances in quantum metrology and sensing. In…
Harnessing coherence generation for precision single- and two-qubit quantum thermometry
Youssef Aiache, Abderrahim El Allati, Khadija El Anouz
Quantum probes, such as single- and two-qubit probes, can accurately measure the temperature of a bosonic bath. The current investigation assesses the precision of temperature esti…
