Abstract: Many organized efforts across the world are racing to realize the "Quantum Internet" -- the internet of the future that is upgraded to provide an additional service: that of reliably transmitting qubits between distant users. Just like the internet's classical data communications service, the quantum communications service must reliably support many user groups, and support diverse and dynamic applications---each with its unique requirements on the quality of service for transmission of qubits, e.g., rate, latency, fidelity etc. Supporting long-distance quantum communications at high rates and fidelities will require scalable quantum repeaters and quantum-capable satellites for continental-scale quantum connectivity. In this talk, I will describe the underlying theory of quantum networking and quantum repeaters, allude to a few important applications, and give a glimpse of a large effort underway as part of an NSF-funded 10-year engineering research center called the Center for Quantum Networks (CQN). CQN is a highly interdisciplinary effort with research ranging material-science theory to design high-coherence time quantum memories, quantum memory design and fabrication, building efficient interfaces between matter and photon qubits, cryogenic compatible packaging capabilities, quantum error correction theory to design codes for quantum communication and entanglement distillation, repeater architecture design and analysis, the entire network protocol stack up to the application layer, and finally network control, tomography and management protocols. I will also describe how CQN engages disciplines such as law and policy, social and behavioral sciences and economics through a research thrust focusing on societal impacts of the quantum internet.
Bio: Saikat Guha is the Peyghambarian Endowed Chair Professor of Optical Sciences at the Wyant College of Optical Sciences, at the University of Arizona, with joint appointments with the Department of Electrical and Computer Engineering and the Program in Applied Mathematics. Saikat is the Director of the Center for Quantum Networks, an NSF Engineering Research Center aimed at architecting the quantum internet. Saikat earned his B.Tech. degree in Electrical Engineering in 2002 from the Indian Institute of Technology Kanpur (India), followed by S.M. and Ph.D. degrees in Computer Science at the Massachusetts Institute of Technology. He was with the Quantum Information Processing group at Raytheon BBN Technologies, in Cambridge MA, from 2008 to 2017, where in his most recent role as Lead Scientist, led various sponsored projects in topics revolving quantum enhancements in photonic information processing. His research interests span information and estimation theory, quantum enhanced optical communication and sensing, photonic quantum computing, and network theory. He represented India at the International Physics Olympiad in 1998, where he was awarded the European Physical Society award for the experimental component. He was a co-recipient of an honorable mention in US National Security Agency's best paper in cybersecurity award for his work on quantum secured covert communications. His DARPA Information in a Photon team won the Raytheon 2011 Excellence in Engineering and Technology Award, Raytheon's highest technical honor, for outstanding research on fundamental limits of optical communication
