Saikat Guha is a University of Arizona College of Optical Sciences professor. He is also the director of the National Science Foundation (NSF) Engineering Research Center for Quantum Networks. Guha earned his bachelor’s degree in electrical engineering from the Indian Institute of Technology in Kanpur and his master’s and doctorate in electrical engineering and computer science from the Massachusetts Institute of Technology. From 2008 to 2017, he worked for Raytheon BBN Technologies; as lead scientist, he led various sponsored projects funded by the Defense Advanced Research Projects Agency, the Office of Naval Research, NSF, the Department of Energy, and the Army Research Laboratory (ARL), in topics surrounding quantum enhanced photonic information processing.

Guha’s research interests are in the quantum limits of optical communications and quantum-secured communications (rate) and optical sensing (resolution)—both in the evaluations of these fundamental limits using tools from quantum information and estimation theory, as well as in the associated circuit synthesis problem, that of trying to piece together familiar classical and non-classical optical building blocks to realize transmitters and receivers needed to attain those limits. He is interested in the design of quantum repeaters for long-distance entanglement distribution and has also recently been interested in continuous variable photonic quantum computing and quantum networks.
