Exponentially-improved effective descriptions of physical bosonic systems
Varun Upreti, Nicolás Quesada, Ulysse Chabaud
The effective description of a bosonic quantum system identifies the minimum finite dimension required to capture its essential dynamics. This effective dimension plays an importan…

Optimal Waveforms for Dipole Moment Estimation with Coherent States
Karthik Chinni, Nicolás Quesada
We investigate quantum sensing for spectroscopy in a system consisting of a two-level atom coupled to a continuum of modes. We focus on optimizing the pulse shape of a coherent sta…
