Equilibrium thermometry in the multilevel quantum Rabi model
Tabitha Doicin, Luis A. Correa, Jonas Glatthard +2
The temperature sensitivity of a probe in equilibrium can be gauged by its thermal quantum Fisher information (QFI). It is known that probes exhibiting degeneracy in their energy-l…
On the role of symmetry and geometry in global quantum sensing
Julia Boeyens, Jonas Glatthard, Edward Gandar +3
Global quantum sensing enables parameter estimation across arbitrary ranges with a finite number of measurements. Among the various existing formulations, the Bayesian paradigm sta…
Accurate heat currents via reorganised master equation
Jonas Glatthard, Guillem Aznar-Menargues, José P. Palao +2
The accurate characterisation of energy exchanges between nanoscale quantum systems and their environments is of paramount importance for quantum technologies, and central to quant…
Potential renormalisation, Lamb shift and mean-force Gibbs state -- to shift or not to shift?
Luis A. Correa, Jonas Glatthard
Often, the microscopic interaction mechanism of an open quantum system gives rise to a `counter term' which renormalises the system Hamiltonian. Such term compensates for the disto…
Energy measurements remain thermometrically optimal beyond weak coupling
Jonas Glatthard, Karen V. Hovhannisyan, Martí Perarnau-Llobet +2
We develop a general perturbative theory of finite-coupling quantum thermometry up to second order in probe-sample interaction. By assumption, the probe and sample are in thermal e…
Bending the rules of low-temperature thermometry with periodic driving
Jonas Glatthard, Luis A. Correa
There exist severe limitations on the accuracy of low-temperature thermometry, which poses a major challenge for future quantum-technological applications. Low-temperature sensitiv…
Optimal cold atom thermometry using adaptive Bayesian strategies
Jonas Glatthard, Jesús Rubio, Rahul Sawant +3
Precise temperature measurements on systems of few ultracold atoms is of paramount importance in quantum technologies, but can be very resource-intensive. Here, we put forward an a…
