Adriana Lita (Fed)

Adriana E. Lita is a member of the Faint Photonics Group at NIST-Boulder where she works on fabrication and development of single-photon detectors such as transition-edge sensors (TES) and superconducting nanowires single-photon detectors (SNSPD) devices. Her work includes development of record high quantum efficiency TES devices optimized at various wavelengths from UV to near IR, integration of TES with optical waveguides platforms for photonic circuits, as well as materials development for SNSPDs. These single-photon detectors are the building blocks for applications ranging from testing fundamental laws of quantum mechanics to metrology of quantum light states and implementations of photonic quantum computing.
