Senior Scientist

Saikat Guha is a Senior Scientist and Principal Investigator with the Quantum Information Processing (QuIP) group at Raytheon BBN Technologies in Cambridge, MA. He received his B.Tech. in Electrical Engineering from Indian Institute of Technology (IIT) Kanpur in May 2002, and S.M. in EECS from MIT in February 2004 with a thesis on capacities of free-space quantum optical communication channels. Saikat represented India as a part of the first Indian team of five students at the 29th International Physics Olympiad at Reykjavik, in July 1998 where he received the European Physical Society (EPS) award for the experimental component. He carried out his doctoral research under the supervision of Prof. Jeffrey H. Shapiro at the Optical and Quantum Communications Group of Research Laboratory of Electronics (RLE), MIT. He earned his Ph.D. in June 2008 from the department of EECS, MIT, with a thesis on multiple-user quantum information theory for quantum-optical channels. His current research interests include fundamental limits of single and multiple-user quantum-limited optical communications, quantum Shannon theory, quantum limits to optical sensing, network information theory, and quantum error correction.
