Quantum sensors assisted by spontaneous symmetry breaking for detecting very small forces
journal contribution
posted on 2023-06-09, 01:27 authored by Peter A Ivanov, Kilian Singer, Nikolay V Vitanov, Diego PorrasWe propose a quantum-sensing scheme for measuring weak forces based on a symmetry-breaking adiabatic transition in the quantum Rabi model. We show that the system described by the Rabi Hamiltonian can serve as a sensor for extremely weak forces with sensitivity beyond the yoctonewton (yN) per sqrt (Hz) range. We propose an implementation of this sensing protocol using a single trapped ion. A major advantage of our scheme is that the force detection is performed by projective measurement of the population of the spin states at the end of the transition, instead of the far slower phonon number measurement used hitherto.
