Fundamental limits in Bayesian thermometry and attainability via adaptive strategies

Mohammad Mehboudi, Mathias R. Jørgensen, Stella Seah +3

We investigate the limits of thermometry using quantum probes at thermal equilibrium within the Bayesian approach. We consider the possibility of engineering interactions between t…

Bayesian quantum thermometry based on thermodynamic length

Mathias R. Jørgensen, Jan Kołodyński, Mohammad Mehboudi +2

In this work, we propose a theory of temperature estimation of quantum systems, which is applicable in the regime of non-negligible prior temperature uncertainty and limited measur…

A discrete memory-kernel for multi-time correlations in non-Markovian quantum processes

Mathias R. Jørgensen, Felix A. Pollock

Efficient simulations of the dynamics of open systems is of wide importance for quantum science and tech-nology. Here, we introduce a generalization of the transfer-tensor, or disc…

Tight bound on finite-resolution quantum thermometry at low temperatures

Mathias R. Jørgensen, Patrick P. Potts, Matteo G. A. Paris +1

Precise thermometry is of wide importance in science and technology in general and in quantum systems in particular. Here, we investigate fundamental precision limits for thermomet…

Exploiting the causal tensor network structure of quantum processes to efficiently simulate non-Markovian path integrals

Mathias R. Jørgensen, Felix A. Pollock

In the path integral formulation of the evolution of an open quantum system coupled to a Gaussian, non-interacting environment, the dynamical contribution of the latter is encoded…
