Criticality of quantum energy teleportation at phase transition points in quantum field theory
arXiv:2301.11712 · doi:10.1103/PhysRevD.107.L071502
Abstract
Quantum field theory can be a new medium for communication through quantum energy teleportation. We performed a demonstration of quantum energy teleportation with a relativistic fermionic field theory of self-coupled fermions, called the massive Thirring model. Our results reveal that there is a close relation between the amount of energy teleported and the phase diagram of the theory. In particular, it is shown that the teleported energy peaks near the phase transition points. The results provide new implications for phase diagrams of field theory in terms of quantum communication and quantum computing.
