Description
The Quantum Monte Carlo Sign Problem: Structure, Complexity, and New Directions is a workshop hosted by the Institute for Pure and Applied Mathematics (IPAM) at UCLA, scheduled for January 25–29, 2027. The event will bring together experts from physics, applied mathematics, quantum information, and theoretical computer science to address the persistent challenge of the Monte Carlo sign problem in quantum many-body simulations. The program emphasizes both conceptual progress and practical mitigation strategies, aiming to clarify structural principles behind sign-free formulations, explore new algorithmic and complexity-theoretic directions, and foster collaborative research. Activities include lectures, tutorials, focused discussions, and a poster session. The workshop is particularly supportive of early-career researchers and aims to promote diversity in the mathematical sciences.
