Ultracold polar molecules are an exciting platform for quantum science and technology. The combination of rich internal structure of vibration and rotation, controllable long-range dipolar interactions and strong coupling to applied electric and microwave fields has inspired many applications. These include quantum simulation of strongly interacting many-body systems, the study of quantum magnetism, quantum metrology...
The Ion Storage Group at NIST has developed several generations of optical atomic clocks based on quantum logic spectroscopy of the 1S0–3P0 transition in 27Al+. The latest version of this system began operation last year and achieves higher stability, longer continuous run times and lower systematic uncertainty than previous versions. In this talk I will review the quantum-logic...

Interactions mediated by a surrounding medium appear across physics, from magnetic impurities in metals to fundamental particles mediated by gauge bosons. Such interactions is particularly enhanced in a heavy boson-light fermion mixture. In a series of experiments, we observe fermion-mediated interactions and scattering resonance, which connects the Ruderman-Kittel-Kasuya-Yosida mechanism, polaron interactions and Efimov physics in...
1D gases with point contact interactions are integrable many-body systems, which means that they have many extra conserved quantities, beyond the usual few (energy, momentum, etc.). I will explain integrability in more detail and then show how we make bundles of 1D Bose gases in the lab, the various ways we excite them out of...
The realization of fast and high-fidelity entanglement between separated arrays of neutral atoms would enable a host of new opportunities in quantum communication, distributed quantum sensing, and modular quantum computation. In this talk, I will describe two approaches we are pursuing to generate fast and high-fidelity remote entanglement. In the first approach, we have demonstrated...
