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…
Emission and Absorption of Microwave Photons in Orthogonal Temporal Modes across a 30-Meter Two-Node Network
Alonso Hernández-Antón, Josua D. Schär, Aleksandr Grigorev +6
The tunable interaction between stationary quantum bits and propagating modes of light allows for the encoding of quantum information in the state of itinerant photons. This abilit…
Quantum metrological advantage of high-order squeezed states
Rubén Gordillo-Hachuel, Erik Torrontegui, Cristina de Dios +1
Quantum correlations can be harnessed to improve the precision in parameter estimation beyond classical capabilities. Under a standard interferometric or rotation protocol, it is w…
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…
