Masahiro Hotta, Jiro Matsumoto and Go Yusa propose quantum energy teleportation in a massless field with one spatial dimension, using local operations and classical communication after preparing a correlated state. Their vacuum-state bound limits extractable energy inversely with separation; a specially prepared squeezed state can overcome it. The distance-independent result requires changing that state with distance, while a fixed squeezing parameter retains long-distance decay. Alice's measurement injects energy, and positive excitation energy in the squeezed region supports the negative-energy region created when Bob extracts energy. The paper proposes a quantum Hall edge-current implementation, with state preparation and energy resources essential to the result; it does not report a demonstrated long-distance energy-transfer device.
