Abstract: Quantum energy teleportation is a theoretical concept in quantum physics that describes the transfer of energy from one location to another without the need for a physical medium to carry it. This is made possible by means of universal properties of quantum entanglement and measurement of quantum states.

The role of QET in physics and information engineering is largely unexplored, as the theory has not received much attention for long time since it was proposed about 15 years ago. To validate it on a real quantum processor, my research has tested the energy teleportation protocol in its most visible form for the first time on IBM's superconducting quantum computer. In my seminar, I will explain the historical background of quantum energy teleportation, quantum circuits and quantum operations. Moreover I will present a concrete setup for a long-distance and large-scale quantum energy teleportation with USB/BNL quantum network (~150 km) in Long Island, NY.

Furthermore, as a study based on the high-energy physics perspective of quantum energy teleportation, I will present the results of quantum simulations with relativistic field theory. I turns out that phase diagram of the field theory is closely related with teleportation of energy.

In summary my talk will provide a novel suggestion that quantum energy teleportation paves a new pathway to a link between quantum communication on real quantum network, phase diagram of quantum many-body system, and quantum computation.
