Nonlocal correlations in quantum energy teleportation: perspectives from their Majorana representations and information thermodynamics
Hiroaki Matsueda, Yusuke Masaki, Kanji Itoh +2
Motivated by anomalous nonlocal correlation in the Kitaev spin liquids, we propose a quantum energy teleportation protocol between remote partners Alice and Bob on a quantum spin m…

Upper Bound on Locally Extractable Energy from Entangled Pure State under Feedback Control
Kanji Itoh, Yusuke Masaki, Hiroaki Matsueda
We introduce an effective thermodynamics for multipartite entangled pure states and derive an upper bound on extractable energy with feedback control from a subsystem under a local…

Quantum Energy Teleportation and Entropy Change due to Feedback Control in One-Dimensional Heisenberg Model
Kanji Itoh, Yusuke Masaki, Hiroaki Matsueda
We study the quantum energy teleportation in a four-spin one-dimensional Heisenberg model. A local magnetic field is applied at the edge sites to control the degree of the ground-s…
