Quantum gravity is concerned with the search for consistent models of quantum spacetime and the experimental challenge of determining which model describes nature. Experimental access to the quantum physics of spacetime is still challenging, but we are currently seeing dramatic advances in our theoretical understanding of quantum gravity.

These developments are occurring primarily in the context of so-called holographic models like the AdS/CFT correspondence, with ideas from quantum information science and many-body physics, including information scrambling, tensor networks, and quantum error correction codes, playing a central role. Moreover, there is the exciting possibility that such models of quantum gravity can be experimentally studied in the near future using quantum simulators.

This tutorial will introduce some of the organizing ideas and open questions in the field of quantum gravity and describe how ideas ranging from computational complexity to quantum codes are being used to understand how spacetime can emerge from microphysics.


  • Scrambling, complexity, and black holes
  • Geometry from entanglement and quantum codes
  • Tensor network models of spacetime
  • Experimental probes of emergent geometry

Who Should Attend?

Graduate students, post-docs, and other scientists interested in learning about the ongoing developments at the interface of quantum gravity, quantum information, and many-body physics. The field is quite broad, involving inputs from high energy physics, quantum information science, and condensed matter physics, and anyone interested in learning the basics is encouraged to attend regardless of background. The tutorial talks will be very pedagogical, describing some of the key problems in the field and the tools currently being used to address them, with a focus on simple models of the physics.
