Our New Vacuum Setup is Ready!
Our TwEQEzer apparatus is ready to capture and cool down single atoms
At the end of February 2025, we reached another major milestone in exploring the frontiers of quantum science: our second vacuum setup is now ready to realize a novel quantum processing architecture based on dual-element, dual-type atom arrays.
Nicknamed TwEQEzer, this new apparatus will host a programmable quantum processor designed for rapid operations and error correction in an ultra-high vacuum environment of ~10⁻¹² mBar. Complementary to our first experimental setup, PaInt—which focuses on investigating pairwise interspecies Rydberg interactions and establishing a strong atom-light interface with Rydberg polaritons—TwEQEzer is built to push the state-of-the-art in quantum simulation and quantum information processing.
After months of planning, debugging, and overcoming unexpected challenges, we finally tightened the last screw and completed a successful bakeout. In the images below, you can see the result of our hard work—a gleaming glass cell with precisely assembled electrodes, put together with surgical precision.
Our next focus is bringing our 2D and 3D MOTs, and we cannot wait to see the first single atoms glowing in our glass cell—it is going to be an exciting moment! Meanwhile, a theoretical paper outlining the novel schemes enabled by this architecture is already in preparation. Stay tuned!
