Quantum Meets Classical

Workshop Report

The goal of this workshop was to bring together scientists working at the interface where quantum systems meet the classical world. This is a broad area but several scientific clusters naturally emerged in the course of the workshop, reflecting the state of the field. Broadly, these themes included  

- simulating quantum and classical statistical mechanical phases and phase transitions on current quantum processors;
- the emergence of both normal and anomalous hydrodynamic descriptions from quantum dynamics (primarily in 1D);
- methods to generate useful entanglement from hydrodynamic processes;
- the complex relationships between semi-classical dynamics, scars, chaos and entanglement generation;
- the physics and mathematics of random unitary and monitored circuits;
- classical computational techniques exploiting entanglement and symmetry to simulate quantum phases and dynamics;
- Anderson localization in high dimensions and its relationships with coding.

The workshop kicked off on Monday evening with a colloquium and welcome dinner, which set the stage for the primary series of 24 talks spread over the next four days. Talks were allocated longer format 45 minute slots, which enabled speakers to provide pedagogical introductions with ample space for questions, of which there were many. Some 26 contributed posters anchored the evening poster sessions on Tuesday and Thursday, which were well attended and busy with discussion. These were an especially useful opportunity for junior participants to present their work and interact with other participants. Finally, the Wednesday afternoon hike in the Sächsische Schweiz was a perfect, anomalously sunny and beautiful, break and setting for longer informal discussions.
