The Key Exchange Problem: Cryptography in the Quantum Computing Era

 SEC's July Presentation: As quantum computers become more powerful, even our most secure methods for encrypting and sending data will become vulnerable. This is most apparent with the key exchange problem—how do we establish a secure communication channel to exchange information even in the presence of eavesdroppers with the world’s most sophisticated decryption tools? Quantum cryptography offers a solution to this problem with security guaranteed by the laws of quantum mechanics. In this talk, our speaker will provide an overview of quantum cryptography and its importance in the age of quantum computing. He will present exciting developments in space-based communications, metropolitan quantum networks, entanglement, and miniaturized quantum cryptography devices.

Our Speaker: Galan Moody is an Assistant Professor in the Electrical and Computer Engineering Department at UCSB. His research group develops quantum photonic technologies for computing, communications, networking, and metrology. He is a recipient of an NSF CAREER award (2021) and an Air Force Young Investigator Program Award (2020). Dr. Moody is on the executive committee and is a thrust co-lead in the UCSB Quantum Foundry, the faculty leadership committee for the Institute of Energy Efficiency, and the editorial board for the Journal of Physics: Photonics. He has a BSc in Engineering Physics and a PhD in Physics both from the University of Colorado in Boulder. More information on his group’s research can be found at qpl.ece.ucsb.edu.
