Abstract

We propose a novel timelike quantum energy teleportation (QET) protocol within the 1+1 dimensional Nambu-Jona-Lasinio (NJL) model, an interacting fermionic field theory exhibiting spontaneous chiral symmetry breaking. By coupling localized Unruh-DeWitt detectors to the fermionic field, we demonstrate how an initial observer's measurement enables a second observer to extract energy at a later time using only classical information transfer. This protocol leverages the NJL vacuum's rich entanglement structure, driven by the chiral condensate, to facilitate energy transfer without physical particle transport. We derive the energy flows and explore the roles of measurement and time evolution and validate the protocol through quantum circuit simulations on a lattice-regularized NJL model. Our findings highlight the NJL model's potential as a platform for exploring QET in interacting quantum field theories and pave the way for experimental realizations on quantum hardware.
