Differential magnetometry with partially flipped Dicke states
Iagoba Apellaniz, Manuel Gessner, Géza Tóth
We study magnetometry of gradients and homogeneous background fields along the three orthogonal directions using two spatially separated spin ensembles. We derive trade-off relatio…

Lower Bounds on Quantum Metrological Precision
Iagoba Apellaniz
In this thesis, first, we investigate the metrological usefulness of a family of states known as unpolarized Dicke states, which turn to be very sensitive to the magnetic field. Qu…
