Title: Quantum Money: From Algebraic Geometry to Modular Forms

Abstract: Quantum money is the quantum-mechanical counterpart of classical money, where bills are represented by quantum states. Due to the fundamental no-cloning theorem, such bills cannot be counterfeited. The invention of quantum money is widely regarded as one of the earliest conceptual foundations of quantum information science. In recent years, many proposals for public-key quantum money have been put forward; however, each of these schemes has either been broken or relies on non-standard cryptographic assumptions. Despite these efforts, constructing public-key quantum money based on standard cryptographic assumptions remains elusive. In this talk, I will discuss several aspects of public-key quantum money and explain the mathematics underlying two representative schemes.
