Workshop III: Many-body Quantum Systems via Classical and Quantum Computation

6 November - 9 November

The ability to coherently manipulate complex quantum many-body states offers the potential for dramatic improvements in a wide range of applications such as fast computation, enhanced sensing, and secure communications. However, understanding and ultimately controlling the dynamics of such entangled quantum states pose a number of challenges in mathematics and physics. In particular, the description of such complex quantum states often lies beyond the standard approach used in different areas of physics owing to their rich complexity.

This workshop is devoted to the related questions of how quantum and classical computers can be used to address important problems in quantum many-body physics, ranging from simulating quantum chemistry to understanding information dynamics in quantum circuits. While the faithful representation of full many-particle Hilbert spaces on a classical computer is exponentially costly, efficient approximate descriptions for specific purposes have been developed such as tensor network representations or mapping random circuits to statistical mechanics models. Also, recent advances of quantum technologies enable the empirical investigation of previously unexplored regimes of physics with high complexity, demanding new approaches to robustly controlling and utilizing near-term quantum devices for scientific discoveries and practical applications. This workshop will report the status quo of these developments and facilitate discussions for future research directions.

This workshop will include a poster session; a request for posters will be sent to registered participants in advance of the workshop.

This is a Julian Schwinger Workshop on Multiscale Physics, made possible by a gift from the Julian Schwinger Foundation for Physics Research (JSF).
