IAS Program on Particle Theory

Quantum Information Science – Topics about Post-quantum Cryptography


In this lecture, the speaker will introduce (if time allows) the basic concepts of post-quantum cryptography (PQC), including the learning with error (LWE) problem, lattice-based cryptography (LWE, Ring-LWE and brief introduction to crystal-kyber), and hash-based cryptography (Lamport signatures, Merkle trees and SPHINCS), and how PQC could be potentially used to enhance quantum technologies.


About the Speaker

Dr. LIU Junyu is an incoming assistant professor of computer science in the University of Pittsburgh, USA. He earned his PhD in Physics from the California Institute of Technology in 2021, and his bachelor's degree in physics from University of Science and Technology of China in 2016. In 2021-2024 he worked as a postdoc fellow with the University of Chicago and IBM. He also served as a co-founder of SeQure, a company for AI and cryptography starting from 2022. Dr. Liu has a keen interest in the combination of physics and computing, especially machine learning and quantum technologies. His work encompasses areas such as quantum machine learning, quantum error correction, quantum communication and quantum networks.
