Abstract: “The recent acceleration of progress in quantum technology has had mixed effects on the field of cryptography. On one hand, the possibility of a fully functioning quantum computer threatens the security of protocols that are in use today for public-key encryption. On the other hand, the existence of quantum technology has opened the door to a newer kind of cryptography: one that is based only on physical assumptions rather than computational assumptions. A seminal example of this alternative form of cryptography is a quantum key distribution (secure communication across a quantum channel in the presence of a computationally unlimited adversary).

Quantum cryptography originated in the 1980s, and — partly because it so different from what came before — new advances require innovation from both theorists and experimentalists. This talk will be about mathematical and theoretical problems that arise in quantum cryptography. I will discuss two examples from my own work: device-independent random number generation and two-party coin-flipping.”

Biography: “Carl Miller is a member of the Joint Center for Quantum Information and Computer Science (QuICS) and a Mathematician in the Computer Security Division at NIST. His research is on developing new cryptography for the quantum era. Miller’s work on quantum random number generation has been featured in STOC, the Journal of the ACM, and Physical Review Letters. Other topics of interest include quantum cryptographic protocols between mutually mistrustful parties and classical “postquantum” cryptographic protocols. Miller also studies applications to quantum information of concepts that originated in pure mathematics.

Miller received a Ph. D. in mathematics from Berkeley in 2007, and was a research fellow in the Electrical Engineering and Computer Science Department at the University of Michigan before joining QuICS.”
