December 16, 2020: Our new paper on scalable, coherent tweezer clocks is published in Nature!

In this work, we showed half-minute scale coherence in a tweezer clock of 150 atoms, demonstrated high relative stability, and established new methods for scaling ultracold arrays of neutral atoms. Congratulations to the team! See also: The Nature highlight on our work and the recent entangled optical clock paper from the Vuletić group; and, NIST highlight.

A new national quantum research center draws on JILA Fellows' and their expertise to make the United States an international leader in quantum technology.

June 10, 2020: Our new paper on scalable tweezer clocks is posted!

In this most recent paper, we show how to scale tweezer arrays to 320 sites, while maintaining atomic coherence at the half-minute-scale. This allows us to reach excellent stability through frequency self-comparisons in the array, as well as to characterize the single-particle coherence in the array through correlation measurements.

In September, Aaron installed a camera to assemble a timelapse of the lab's development --- it takes a picture every 30 minutes from a corner in the ceiling. Here are some shots from that over the past 4 months, as well as some closeups of our new science system!
