Entanglement-assisted atomic clock beyond the projection noise limit
Anne Louchet-Chauvet, Jürgen Appel, Jelmer J. Renema +3
We use a quantum non-demolition measurement to generate a spin squeezed state and to create entanglement in a cloud of 10^5 cold cesium atoms, and for the first time operate an ato…

Quantum noise limited and entanglement-assisted magnetometry
W. Wasilewski, K. Jensen, H. Krauter +3
We study experimentally the fundamental limits of sensitivity of an atomic radio-frequency magnetometer. First we apply an optimal sequence of state preparation, evolution, and the…
