Quantum uncertainty limits sensitivity in some of our best optical measurements, while quantum engineering is beginning to offer breakthroughs in measurement precision. We aim to use interferometry to translate the wave-particle quantum nature of light and matter into higher sensitivity measurements for fundamental physics.

LIGO: Laser Interferometer Gravitational-wave Observatory

Over much of LIGO's detection band, quantum noise limits detector sensitivity. We're working with the global effort to expand the quantum-limited astrophysical horizons of ground-based gravitational-wave detectors.

As part of the LIGO Scientific Collaboration at Berkeley, we are developing technologies to enable higher levels of broadband, tunable, and robust frequency-dependent squeezing.

Atom interferometry for precision gravimetry

We aim to strongly couple a trapped atom interferometer to an optical cavity for precision gravimetry at the limit of macroscopic quantum coherence.
