I am a staff physicist in the Ion Storage Group at NIST Boulder. My research focuses on quantum information experiments with trapped atomic ions, with an emphasis on developing new paradigms for scalable trapped ion quantum computing. Recent projects include performing high-fidelity two-ion entangling operations with microwave and rf fields instead of lasers, achieving entangled state fidelities rivaling those from best laser-based gates; using strong unitary squeezing of ion motion to enhance ion-ion interactions and to perform electric field sensing below the standard quantum limit; and integrating superconducting photon detectors into microfabricated ion traps (made in the world-class NIST Boulder Microfabrication Facility, in collaboration with the NIST Faint Photonics Group) as an initial step in building a fully chip-integrated trapped ion quantum processor. In my previous research life, I worked in superconducting quantum information, where I performed the first continuous high-fidelity measurement of a superconducting qubit, and studied quantum feedback, measurement backaction, and near-quantum-limited parametric amplification.

The research in our group is carried out by an international team of staff scientists, postdocs, and graduate students. We are always looking for bright, motivated people to join us. Please contact me to discuss opportunities.

An up-to-date listing of my publications is available on Google Scholar or the arXiv.
