CUA Seminar – Adam Kaufman: New frontiers in atom arrays using alkaline-earth atoms

Location:MIT 6-120
Adam Kaufman, University of Colorado Boulder

Quantum science with neutral atoms has seen great advances in the past two decades. Many of these advances follow from the development of new techniques for cooling, trapping, and controlling atomic samples. As one example, the technique of optical tweezer trapping of neutral atom arrays has been a powerful tool for quantum simulation and quantum information, because it enables scalable control and detection of individual atoms with switchable interactions. In this talk, I will describe ongoing work at JILA where we have explored a new type of atom — two-electron atoms — for optical tweezer trapping. While their increased complexity leads to challenges, these atoms also offer new scientific opportunities, such as new detection/preparation schemes, new optical clock architectures, new qubit modalities, and new entanglement protocols in novel degrees of freedom. Accordingly, this new direction has had broad impact on neutral atom quantum science, in areas ranging from quantum information processing,  to many-body physics and quantum metrology. I will report on my group’s progress in these areas, which is based on two experiments, one with bosonic strontium and another with fermionic Ytterbium.
