After extensive rebuild of the main experiment and the cooling laser systems we have found the 2D magneto-optical trap (MOT) again!

The first step in all our future quantum-computing runs will be to cool and trap atoms in a vertical 2D MOT. This is operated on the broad ¹S₀ - ¹P₁ transition, enabling us to capture a large number of atoms. Next, atoms fall down into and are captured by the 3D MOT, which we are currently preparing.

Single Fermionic Yb atoms in optical tweezers

After successful optimization of trapping and imaging of individual bosonic 174Yb atoms we have now succeeded in trapping fermionic 173Yb atoms in triple (1S0, 3P0, 3P1) magic optical tweezers at 759nm using the magic angle for the polarization of the tweezer light.

First single Yb atoms in optical tweezers in Hamburg!

For the first time we have loaded individual 174Yb atoms in a small tweezer array at a wavelength of 532nm. Atoms are imaged on the 1S0 -3P1 transition.
