Prof. Shahriar's group uses atomic and optical systems for precision measurement and quantum information. Key directions: (1) White-light cavities — using anomalous dispersion media inside optical cavities to create a bandwidth-extended cavity enabling broadband gravitational wave detector sensitivity enhancement beyond current LIGO designs; (2) Superluminal (fast-light) gyroscopes — anomalous-dispersion-enhanced ring-laser gyroscopes for measuring the Lense-Thirring frame-dragging effect as a test of general relativity, with >10⁶× sensitivity enhancement over conventional Sagnac gyroscopes; (3) Quantum memories and computers using trapped atomic ensembles (PRISM protocol); (4) Ultra-low-light nonlinear optics with nanofibers and atoms for optical switching and quantum logic; (5) Holographic and polarimetric image processing. Member of LIGO Scientific Collaboration; contributed to GW170817 binary neutron star merger discovery. AT&T Professor of ECE.

Emil Zeuthen works on theoretical quantum optomechanics and quantum transduction. Research focuses on (1) figures of merit and protocols for quantum transducers (mechanical interfaces between microwave and optical domains); (2) back-action-evading measurements using optomechanical systems; (3) quantum limits for gravitational wave detection with mechanical systems in a negative-mass spin reference frame. Key QUANTOP theory collaborator bridging optomechanics and quantum sensing.
