Ever since Einstein, physicists have argued about whether time travel is consistent with the laws of physics, and, if so, how it might be accomplished. This talk presents a new theory of time travel based on quantum teleportation. Unlike previous theories, the theory can be tested experimentally. I report on an experimental realization of the 'grandfather paradox': we send a photon a few billionths of a second backwards in time and have it try to 'kill' its previous self.

Quantum superconducting circuits are nanostructured superconducting electrical networks with Josephson junctions. At low temperatures, their quantum dynamics is properly described by using a few degrees of freedom with a collective character. The parameters in the Hamiltonian depend on the dimensions and topology of the circuit; superconducting quantum circuits therefore behave as artificial atoms.
