Organized by Shamit Kachru (Stanford University), Hirosi Ooguri (Caltech) and Subir Sachdev (Harvard University), this is the third symposium on this topic.

Since the first symposium in 2013, quantum entanglement has become even more important in a broad area of theoretical physics ranging from condensed matter physics and quantum information toquantum gravity and string theory. It does appear that the symposia anticipated this impact, and played a role in developing some of the connections between different branches of theoretical physics. Quantum entanglement and its relation toquantum error correction is playing a key role in our understanding of bulk reconstruction in holography. The connections between black holes, fast scrambling, and quantum chaos are other subjects we plan to discuss at the symposium. In particular, the Sachdev-Ye-Kitaev model has been found to be maximally chaotic and seems to provide a solvable model of holography in which the boundary quantum theory is tractable in a regime which captures the subtle correlations in Hawking radiation. In condensed matter physics, entanglement acts as one of the few `tags’ for topologically ordered states, novel phases of matter not characterized by conventional order parameters. This has been particularly powerful in studies of gapped systems.

More recently, a rich web of dualities was discovered in 2+1 dimensions relating some of the simplest critical theories of interest in condensed matter physics. These dualities may be useful in improving understanding of central ideas such as ‘flux attachment’ and the physics of the composite Fermi liquid. All of these recent developments make it an excellent time to bring together theorists in these areas to share their insights and tools.
