As promised, we are back with a green MOT! While careful optimization is still needed, we are happy to report that we have now obtained a green MOT of 174Yb atoms. We are able to switch among different Yb isotopes with ease, so a 171Yb MOT is also in the workings. In the meantime, here is an absorption image of about 2 million trapped Yb atoms. While optimizing the green MOT we are planning the next steps to trap atoms in optical tweezers! |
Yb atoms in optical tweezers make great qubits! We are building a novel quantum hardware platform based on neutral atoms trapped in reconfigurable optical tweezers. We have chosen Yb atoms due to long coherence time, great tunability and addressability as well as a rich Rydberg structure for implementing multi-qubit quantum gates. Our platform will open up new opportunities to explore novel routes towards fault-tolerant quantum computation.
