10:00 groupe de lecture (Louis Haurie) / 11:15 exposé d'Antoine Bourget -- Title: Has a wormhole been traversed on a quantum computer ? -- Abstract: A few months ago, Jafferis et al published in Nature the article "Traversable wormhole dynamics on a quantum processor". I will try to explain the central theoretical ideas involved in this experiment. This involves the holographic principle which relates quantum gravity (in 2 spacetime dimensions, where the wormhole lives) to quantum mechanics (which can be implemented on an actual quantum computer).
