Faint Photonics Group

The Faint Photonics Group develops new light sources, detectors, and measurement techniques that operate at the few photon limit to address national needs in the areas of quantum information science, remote sensing, long-distance communications, and imaging.

The smallest unit of light is a "photon". Generation, manipulation and measurement of light at or near the fundamental limit of a photon can enhance the performance of many optical systems. Remote sensing, long-distance communications, biological imaging, and quantum information science are some near-term applications that would benefit immensely from better optical components and techniques that work efficiently at few or single photon levels. However, the technologies to generate, manipulate, and detect these states of light are inadequate for the emerging applications. The single photonics and quantum information project staff develops new light sources, detectors, and measurement techniques to address these needs.
