Active SU(1,1) atom interferometry
D. Linnemann, J. Schulz, W. Muessel +5
Active interferometers use amplifying elements for beam splitting and recombination. We experimentally implement such a device by using spin exchange in a Bose-Einstein condensate.…

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…
