Experimental Verification of Position-Dependent Angular-Momentum Selection Rules for Absorption of Twisted Light by a Bound Electron
Andrei Afanasev, Carl E. Carlson, Christian T. Schmiegelow +3
We analyze the multipole excitation of atoms with twisted light, i.e., by a vortex light field that carries orbital angular momentum. A single trapped Ca ion serves as a…
Scalable creation of long-lived multipartite entanglement
H. Kaufmann, T. Ruster, C. T. Schmiegelow +6
We demonstrate the deterministic generation of multipartite entanglement based on scalable methods. Four qubits are encoded in Ca, stored in a micro-structured segmented…
Entanglement-based dc magnetometry with separated ions
T. Ruster, H. Kaufmann, M. A. Luda +4
We demonstrate sensing of inhomogeneous dc magnetic fields by employing entangled trapped ions, which are shuttled in a segmented Paul trap. As \textit{sensor states}, we use Bell…
