Bridging Quantum and Semi-Classical Thermodynamics in Cavity QED
Marcelo Janovitch, Sander Stammbach, Matteo Brunelli +1
In cavity quantum electrodynamics (QED), photons leaving the cavity can be irreversibly lost or reused as a power source. This dichotomy is reflected in two different thermodynamic…
Irreversibility and correlations in coupled quantum oscillators
Matteo Brunelli, Mauro Paternostro
We investigate the link between the irreversibility generated by a stationary dissipative process and the correlations established within a composite quantum system. We provide two…
Path Integral Approach to Input-Output Theory
Aaron Daniel, Matteo Brunelli, Aashish A. Clerk +1
Input-output theory is a well-known tool in quantum optics and ubiquitous in the description of quantum systems probed by light. Owing to the generality of the setup it describes,…
Studying a set of properties of inconsistency indices for pairwise comparisons
Matteo Brunelli
Pairwise comparisons between alternatives are a well-established tool to decompose decision problems into smaller and more easily tractable sub-problems. However, due to our limite…
Stabilization of multi-mode Schrodinger cat states via normal-mode dissipation engineering
Petr Zapletal, Andreas Nunnenkamp, Matteo Brunelli
Non-Gaussian quantum states have been deterministically prepared and autonomously stabilized in single- and two-mode circuit quantum electrodynamics architectures via engineered di…
Qubit-assisted thermometry of a quantum harmonic oscillator
Matteo Brunelli, Stefano Olivares, Mauro Paternostro +1
We use the theory of quantum estimation in two different qubit-boson coupling models to demonstrate that the temperature of a quantum harmonic oscillator can be estimated with high…
