The holographic principle, theorized to be a property of quantum gravity, postulates that the description of a volume of space can be encoded on a lower-dimensional boundary. The anti-de Sitter (AdS)/conformal field theory correspondence or duality 1 is the principal example of holography. The Sachdev–Ye–Kitaev (SYK) model of N≫ 1 Majorana fermions 2, 3 has features suggesting the existence of a gravitational dual in AdS 2, and is a new realization of holography 4, 5, 6. We invoke the holographic correspondence of the SYK many-body system and gravity to probe the conjectured ER= EPR relation between entanglement and spacetime geometry 7, 8 through the traversable wormhole mechanism as implemented in the SYK model 9, 10. A qubit can be used to probe the SYK traversable wormhole dynamics through the corresponding teleportation protocol 9. This can be realized as a quantum circuit …
