Abstract: Cryptographic applications of quantum information have been studied since the pioneering work of Wiesner in 1968 and Bennett and Brassard in 1984. In particular, the uncloneable and uncertain nature of quantum information has proven to be useful for achieving various cryptographic tasks, including information-theoretically secure key agreement. This talk will focus on an application of quantum information to the cryptographic notion of secure computation, which allows mutually distrusting parties to jointly compute functionalities over their private inputs. We will discuss the original proposal for “quantum oblivious transfer” due to Crépeau and Killian in 1988, as well as some recent work that establishes its security based solely on the existence of one-way functions.
Biography: James Bartusek is a computer science PhD student in the theory group at UC Berkeley, where he is advised by Sanjam Garg . His research focuses on various aspects of cryptography, including quantum and post-quantum cryptography.
