Abstract:
Quantum teleportation transfers an arbitrary quantum state between two distant parties using shared entanglement and two bits of classical communication. This raises a natural question: how does the continuous information describing the quantum state travel between the two locations if only two classical bits are transmitted? Different accounts of teleportation answer this question differently, yet they remain empirically indistinguishable in standard implementations.
In this talk we consider the Deutsch-Hayden account, which explains teleportation through a strictly local and causal flow of information. This approach requires the communication channel to be implemented by quantum systems at the fundamental level, even if it appears operationally classical.
This suggests a new experimental possibility. If the two bits were mediated by a fundamentally classical gravitational interaction, would teleportation still succeed? Gravitational teleportation would probe the relationship between local information flow and the quantum or classical nature of gravity.
