Quantum-enhanced sensing using non-classical spin states of a highly magnetic atom

Quantum-enhanced sensing using non-classical spin states of a highly magnetic atom

Moderate-size coherent superpositions of spin states allow quantum enhancements in metrology. Here, the authors exploit the large electronic spin of dysprosium atoms to realize mesoscopic spin superpositions, allowing a 14-fold quantum enhancement in magnetic field sensitivity, close to the Heisenbe...
