- Abstract summary: Recent works have designed a special teleportation protocol that realizes a surprising communication phenomenon.
We have carried out quantum experiments based on this protocol on state-of-the-art quantum computers.
We report the observed teleportation signals from these QPUs with the best one reaching 80% of theoretical predictions.

- Abstract: The holographic principle and its realization in the AdS/CFT correspondence
led to unexpected connections between general relativity and quantum
information. This set the stage for studying aspects of quantum gravity models,
which are otherwise difficult to access, in table-top quantum-computational
experiments. Recent works have designed a special teleportation protocol that
realizes a surprising communication phenomenon most naturally explained by the
physics of a traversable wormhole. In this work, we have carried out quantum
experiments based on this protocol on state-of-the-art quantum computers. The
target quantum processing units (QPUs) included the Quantinuum's trapped-ion
System Model H1-1 and five IBM superconducting QPUs of various architectures,
with public and premium user access. We report the observed teleportation
signals from these QPUs with the best one reaching 80% of theoretical
predictions. We outline the experimental challenges we have faced in the course
of implementation, as well as the new theoretical insights into quantum
dynamics the work has led to. We also developed QGLab -- an open-source
end-to-end software solution that facilitates conducting the wormhole-inspired
teleportation experiments on state-of-the-art and emergent generations of QPUs
supported by the Qiskit and tket SDKs. We consider our study and deliverables
as an early practical step towards the realization of more complex experiments
for the indirect probing of quantum gravity in the lab.
