Abstract: That a quantum computer can be used to break some cryptographic
schemes via Shor’s algorithm is a well-known fact. But which cryptographic
schemes are that? Where are they used? How does a quantum computer actually
solve a computational task like integer factorization so much faster than a
regular computer? In this lecture, I will try to answer these questions. I
will then go on to to discuss a number of approaches for constructing
post-quantum cryptography. Finally, I will show how quantum computing theory
is necessary not only for cryptanalysis, but also for security proofs of
modern cryptographic schemes.

 

Bio: Christian Majenz obtained his master's degree in physics from the
University of Freiburg, supervised by David Gross. He obtained his PhD from
the University of Copenhagen under the supervision of Matthias Christandl,
spending time at Caltech along the way. After a postdoc at the QuSoft Center
and CWI in Amsterdam he moved back to Copenhagen where he is currently an
Assistant Professor at the Technical University of Denmark. His main
research interests are provable security for post-quantum cryptography,
other quantum aspects of cryptography and representation-theoretic
techniques in quantum theory.
