Observation of universal dynamics in a spinor Bose gas far from equilibrium
Maximilian Prüfer, Philipp Kunkel, Helmut Strobel +6
The dynamics of quantum systems far from equilibrium represents one of the most challenging problems in theoretical many-body physics. While the evolution is in general intractable…
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.…
Spatially distributed multipartite entanglement enables Einstein-Podolsky-Rosen steering of atomic clouds
Philipp Kunkel, Maximilian Prüfer, Helmut Strobel +5
A key resource for distributed quantum-enhanced protocols is entanglement between spatially separated modes. Yet, the robust generation and detection of nonlocal entanglement betwe…
Quantum-Enhanced Sensing Based on Time Reversal of Nonlinear Dynamics
Daniel Linnemann, Helmut Strobel, Wolfgang Muessel +4
We experimentally demonstrate a nonlinear detection scheme exploiting time-reversal dynamics that disentangles continuous variable entangled states for feasible readout. Spin-excha…
Fisher Information and entanglement of non-Gaussian spin states
Helmut Strobel, Wolfgang Muessel, Daniel Linnemann +5
Entanglement is the key quantum resource for improving measurement sensitivity beyond classical limits. However, the production of entanglement in mesoscopic atomic systems has bee…
Twist-and-Turn Spin Squeezing in Bose-Einstein Condensates
W. Muessel, H. Strobel, D. Linnemann +3
We experimentally demonstrate an alternative method for the dynamic generation of atomic spin squeezing, building on the interplay between linear coupling and nonlinear phase evolu…
