Dear Qubitzers, GR=QM

Leonard Susskind

Abstract

These are some thoughts contained in a letter to colleagues, about the close relation between gravity and quantum mechanics, and also about the possibility of seeing quantum gravity in a lab equipped with quantum computers. I expect this will become feasible sometime in the next decade or two.

  • Figure 3: The event $\bf a$ is behind the horizon and cannot be seen from the boundary.
  • Figure 4: The protocol of Gao:2016binMaldacena:2017axo makes the wormhole traversable so that $\bf a$ becomes visible from the boundaries. The orange curve represents the classical information sent from Alice to Bob, required to carry out the protocol.
