Three-dimensional imaging of single atoms in an optical lattice via helical point-spread-function engineering
Tangi Legrand, Falk-Richard Winkelmann, Wolfgang Alt +3
We demonstrate a method for determining the three-dimensional location of single atoms in a quantum gas microscopy system using a phase-only spatial light modulator to modify the p…
Achievements and Perspectives of Optical Fiber Fabry-Perot Cavities
Hannes Pfeifer, Lothar Ratschbacher, Jose Gallego +8
Fabry-Perot interferometers have stimulated numerous scientific and technical applications ranging from high resolution spectroscopy over metrology, optical filters to interfaces o…
Tunable Fiber Fabry-Perot Cavities with High Passive Stability
Carlos Saavedra, Deepak Pandey, Wolfgang Alt +2
We present three high finesse tunable monolithic fiber Fabry-Perot cavities (FFPCs) with high passive mechanical stability. The fiber mirrors are fixed inside slotted glass ferrule…
Fast non-destructive parallel readout of neutral atom registers in optical potentials
Miguel Martinez-Dorantes, Wolfgang Alt, Jose Gallego +4
We demonstrate the parallel and non-destructive readout of the hyperfine state for optically trapped Rb atoms. The scheme is based on state-selective fluorescence imaging an…
Ideal negative measurements in quantum walks disprove theories based on classical trajectories
Carsten Robens, Wolfgang Alt, Dieter Meschede +2
We report on a stringent test of the non-classicality of the motion of a massive quantum particle, which propagates on a discrete lattice. Measuring temporal correlations of the po…
A Hidden Markov Model of atomic quantum jump dynamics in an optically probed cavity
S. Gammelmark, W. Alt, T. Kampschulte +2
We analyze the quantum jumps of an atom interacting with a cavity field. The strong atom- field interaction makes the cavity transmission depend on the time dependent atomic state,…
