Research Overview

Our Research Group specializes in theoretical quantum information science (QIS), quantum optics, and atomic-molecular-optical (AMO) physics. We study the foundations of quantum information processing (QIP) and its implementation in AMO systems. Key questions we seek to address include:

  • How much complexity can we harness for QIP in noisy quantum systems without error correction (NISQ devices)?
  • How does dynamical complexity (quantum chaos) relate to computational complexity for QIP?
  • How do we achieve high fidelity control of complex quantum systems?
  • How do we best characterize, verify, and validate the performance of quantum information processors?

We collaborate with investigators across CQuIC in order to bring fundamental ideas and protocols into the laboratory. Together with Prof. P. S. Jessen, we have developed platforms for quantum control, simulation, measurement, feedback, and tomography, based on spins in cold atomic gases. Together with Profs. T. Albash and A. Miyake we study how much quantum advantage we can harness in Noisy Intermediate Scale Quantum (NISQ) devices. With Prof. G. Biedermann (University of Oklahoma) and Prof. Albash, we seek to put this to the test in an experimental platform based on a Cs Rydberg atom QIP. Together with Prof. F. E. Becerra we seek to create complex quantum states of atom ensembles through measurement and feedback. Together with Dr. M. Martin (Los Alamos) we study quantum control of atomic quditsin an experimental platform basedon a Sr Rydberg atom QIP.
