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…

Fidelity bounds for spin-dependent kicks with pulsed lasers
C. Sagaseta, H. Liu, V. D. Vaidya +3
Excitation of trapped-ion hyperfine qubits with fast optical Raman pulses enables faster-than-trap-period entangling gates with qubits of long coherence time for practical quantum…

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…
