Fundamental limits to frequency estimation: A comprehensive microscopic perspective
Jan F. Haase, Andrea Smirne, Jan Kołodyński +2
We consider a scenario in which qubit-like probes are used to sense an external field that linearly affects their energy splitting. Following the frequency estimation approach in w…
Coherence and non-classicality of quantum Markov processes
Andrea Smirne, Dario Egloff, María García Díaz +2
Although quantum coherence is a basic trait of quantum mechanics, the presence of coherences in the quantum description of a certain phenomenon does not rule out the possibility to…
Non-perturbative treatment of non-Markovian dynamics of open quantum systems
Dario Tamascelli, Andrea Smirne, Susana F. Huelga +1
We identify the conditions that guarantee equivalence of the reduced dynamics of an open quantum system (OQS) for two different types of environments - one a continuous bosonic env…
Momentum coupling in non-Markovian Quantum Brownian motion
Luca Ferialdi, Andrea Smirne
We consider a model of non-Markovian Quantum Brownian motion that consists of an harmonic oscillator bilinearly coupled to a thermal bath, both via its position and momentum operat…
