One of science’s great challenges is to reconcile the two theories that form the foundation of modern physics. These are quantum field theory, which governs the universe on the smallest scale, and general relativity, which governs the universe on the largest scale. Together these theories accurately describe phenomena over a forty order of magnitude range.
“This is a surprising result, since one does not expect strongly scrambling systems to be able to transmit classical bits,” say Illya Shapoval at the Lawrence Berkeley National Laboratory in California and colleagues.Just as significant is that this new way of thinking about quantum gravity is surprisingly fruitful. “The process of developing a practical experimental protocol itself led to new theoretical insights into quantum dynamics,” they add.
Physicists call this AdS/CFT correspondence and it is their current best guess about the nature of quantum gravity. However, the potentially testable predictions from this theory are so subtle and on such a small scale that nobody has found a way to observe them, not least because AdS/CFT theories only work in universes that are significantly different from our own.
This is where the new work by Shapoval and co comes in. Although it is not possible to directly observe this phenomenon, “perhaps we can use quantum simulators and quantum computers to indirectly probe quantum gravity in the lab,” they suggest. Just why this is possible isn’t clear. But it provides an avenue for further investigation. In particular, the researchers are curious whether this mechanism offers any advantage in transmitting information in this way. “Our findings raise new questions about potential regimes in AdS/CFT where traversable wormholes can transmit classical but not quantum data,” say the team.
