Dr. Guha's intention in this seminar is to engage with a broad ECE audience on problems tied to leveraging quantum versions of information, detection and estimation theories to delineate fundamental limits in encoding, processing and extracting information in the context of communications and sensing. He will review information-theoretic limits of classical and quantum optical communications and sensing and will show some concrete yet simple examples of how using quantum processing of optically encoded data can yield fundamental improvements over (even idealized) traditional systems. Dr. Guha will discuss a few open problems that might be of interest to ECE faculty in topics surrounding photonic information processing using tools from detection theory, communications theory and error correction.
Dr. Guha is director of the NSF-ERC Center for Quantum Networks and Peyghambarian Endowed Chair Professor of Optical Sciences, Electrical and Computer Engineering and Applied Mathematics at the University of Arizona. He received his bachelor of technology degree in electrical engineering from the Indian Institute of Technology, Kanpur in 1998, and his S.M. and Ph.D. degrees in electrical engineering and computer science from the Massachusetts Institute of Technology in 2004 and 2008, respectively. From 2008 to 2017, Dr. Guha worked for Raytheon BBN Technologies as a lead scientist where he led various sponsored projects funded by DARPA, ONR, NSF, DoE, and ARL, in topics surrounding quantum-enhanced photonic information processing. He was one of the founding members of the Quantum Information Processing group at BBN, formed in 2009.
