He has given invited talks at numerous national and international conferences and has authored more than 100 articles on various topics in quantum optics and quantum information, including several review articles. He is a Fellow of the Optical Society of America and the American Physical Society and an Expert Panel member for both the Quantum Computation and Quantum Cryptography Roadmaps. In 1998, Professor Kwiat was awarded the LANL Fellows Prize for his work on optical studies of quantum information. He has done pioneering research on the phenomena of quantum interrogation, quantum erasure, and optical implementations of quantum information protocols. He is a primary inventor of the world's first two sources of polarization-entangled photons from down-conversion, which have been used for quantum cryptography, dense-coding, quantum teleportation, entanglement distillation, and most recently, optical quantum gates. In January 2001, he joined the Physics faculty as the second Bardeen Chair.
