Thermal screening and critical scaling of quantum energy teleportation in a harmonic chain
Taisanul Haque
We develop a finite-temperature Gaussian-state formulation of quantum energy teleportation in the one-dimensional harmonic chain. For Gibbs states, the optimized measurement-feedba…

Nontrivial bounds on extractable energy in quantum energy teleportation for gapped manybody systems with a unique ground state
Taisanul Haque
We establish an exponentially decaying upper bound on the average energy that can be extracted in quantum energy teleportation (QET) protocols executed on finite-range {gapped} lat…
