Precision Spectroscopy and Quantum Control of Trapped Molecular Ions

Ongoing
Spectroscopy and Quantum Control of Molecular Ions Molecules exhibit vibration and rotation of their nuclei, degrees of freedom not present in atoms, and less stringent selection rules for transitions. This creates experimental challenges and great opportunities for exploring new physics. In this
This image shows a planar rf ion trap designed for experiments with magnetically-driven quantum gates.

Quantum Computing with Trapped Ions

Ongoing
Quantum Computing with Trapped Ions We pursue proof-of-concept experiments in quantum information processing and quantum control with trapped ions. In addition to pushing current limits on traditional quantum gate-based architectures for quantum computing we explore alternative approaches to

Quantum Networking with Trapped Ions

Ongoing
The goal of a quantum network is to establish entanglement as a resource between distant locations. Shared entanglement over long distances may enable distributed quantum computing, quantum-enhanced long-baseline interferometry, the transmission of complex quantum states, or a variety of other

Quantum Simulation and Sensing with Trapped Ions

Ongoing
Entanglement between individual quantum objects exponentially increases the complexity of quantum many-body systems, so systems with more than 30-40 quantum bits cannot be fully studied using conventional techniques and computers. To make progress at this frontier of physics, we are pursuing Feynman

Trapped Ion Optical Clocks

Ongoing
This project uses techniques from quantum information science to enable precision metrology. We use the dipole-forbidden 1S 0 - 3P 0 transition in singly-ionized aluminum as an stable frequency reference (natural linewidth ~8 mHz), which we detect using quantum logic spectroscopy with a second ion
