Global Unitaries and Local Measurements - IPAM at UCLA

Explore the fascinating intersection of quantum physics and topology in this 58-minute lecture by Jeongwan Haah from Microsoft Research. Delve into the concept of global unitaries with lightcones and their topological properties, leading to an examination of quantum cellular automata. Discover how connected components in this space correspond to local unitary circuits and learn about the existence and conjectures surrounding distinct connected components. Investigate a class of local measurement circuits, including those of Floquet codes, and understand how they induce a broader range of locality-preserving unitaries compared to local unitary circuits. Gain insights into cutting-edge research presented at IPAM's Topology, Quantum Error Correction and Quantum Gravity Workshop, recorded on November 29, 2023, at UCLA.
