We have completed the optical setup for the 689 nm laser source that will be employed for further cool the Strontium atoms by a factor of 1000 in a red 3D MOT, in order to reach a temperature of few micro Kelvin. A significant challenge we faced was stabilizing the frequency of the red laser to a very stable and very high finesse ultra-low expansion cavity. |
Rydberg atoms in optical tweezers are great for quantum technologies! We are building the first Italian platform based on programmable arrays of optically trapped neutral atoms. We use strontium, which provides states with long coherence time and state-selective transitions enabling advanced manipulation and readout schemes for novel approaches to quantum simulation and quantum computation.
