Quantum-enhanced sensing of displacements and electric fields with two-dimensional trapped-ion crystals
Abstract
Harnessing quantum mechanical effects is expected to provide an advantage over classical sensing technology. By entangling the center-of-mass motional state of approximately 150 ions trapped in a two-dimensional Coulomb crystal with their collective spin state, Gilmore et al . demonstrate a quantum-enhanced measurement sensitivity of displacement and electric field. Such enhanced sensitivity could, for instance, find application in probing proposed weak interactions between dark matter and normal matter, as well as enhancing gravitational wave detection. —ISO
