Microwave-free vector magnetometry and crystal orientation determination with Nitrogen-Vacancy centers using Bayesian inference
Hilario Espinós, Omkar Dhungel, Arne Wickenbrock +3
Nitrogen-vacancy (NV) centers in diamond provide a solid-state platform for quantum sensing. While optically detected magnetic resonance techniques offer high sensitivity, their re…
Regressions on quantum neural networks at maximal expressivity
Iván Panadero, Yue Ban, Hilario Espinós +3
We analyze the expressivity of a universal deep neural network that can be organized as a series of nested qubit rotations, accomplished by adjustable data re-uploads. While the ma…
Control of open quantum systems via dynamical invariants
Loris Maria Cangemi, Hilario Espinós, Ricardo Puebla +2
In this study, we address the challenge of controlling quantum systems under environmental influences using the theory of dynamical invariants. We employ a reverse engineering appr…
Invariant-based control of quantum many-body systems across critical points
Hilario Espinós, Loris Maria Cangemi, Amikam Levy +2
Quantum many-body systems are emerging as key elements in the quest for quantum-based technologies and in the study of fundamental physics. In this study, we address the challenge…
Fast and robust particle shuttling for quantum science and technology
Luke Qi, John Chiaverini, Hilario Espinós +2
We review methods to shuttle quantum particles fast and robustly. Ideal robustness amounts to the invariance of the desired transport results with respect to deviations, noisy or o…
