Optimal Multiparameter Metrology: The Quantum Compass Solution
Denis V. Vasilyev, Athreya Shankar, Raphael Kaubruegger +1
We study optimal quantum sensing of multiple physical parameters using repeated measurements. In this scenario, the Fisher information framework sets the fundamental limits on sens…
Optimal and Variational Multi-Parameter Quantum Metrology and Vector Field Sensing
Raphael Kaubruegger, Athreya Shankar, Denis V. Vasilyev +1
We study multi-parameter sensing of 2D and 3D vector fields within the Bayesian framework for quantum interferometry. We establish a method to determine the optimal quantum…
Variational spin-squeezing algorithms on programmable quantum sensors
Raphael Kaubruegger, Pietro Silvi, Christian Kokail +5
Arrays of atoms trapped in optical tweezers combine features of programmable analog quantum simulators with atomic quantum sensors. Here we propose variational quantum algorithms,…
Generalized Transfer Matrix States from Artificial Neural Networks
Lorenzo Pastori, Raphael Kaubruegger, Jan Carl Budich
Identifying variational wave functions that efficiently parametrize the physically relevant states in the exponentially large Hilbert space is one of the key tasks towards solving…
