Parameter Estimation in a Continuously Monitored Non-Markovian Quantum System
Erik L. André, Pharnam Bakhshinezhad, Patrick P. Potts +2
Continuous monitoring is a powerful tool for analyzing quantum systems and is increasingly used as a non-demolition technique in quantum metrology. In this context, noisy data acqu…
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…
Global Quantum Thermometry
Jesús Rubio, Janet Anders, Luis A. Correa
A paradigm shift in quantum thermometry is proposed. To date, thermometry has relied on local estimation, which is useful to reduce statistical fluctuations once the temperature is…
