From the article

>The first experimental demonstration of quantum energy teleportation on real quantum hardware has been observed, according to new research that also cites observations of negative energy.
>
>Kazuki Ikeda, a researcher with the Department of Physics and Astronomy at Stony Brook University, New York, says that the breakthrough was achieved with the help of a series of IBM superconducting quantum computers.

>“The methods we have established can be applied to any system capable of [quantum energy transfer]”, Ikeda writes, adding that such methods of energy teleportation can be applied universally, “just as quantum teleportation is a universal means of quantum information transfer.”
>
>In addition to the successful transfer of energy observed in real quantum hardware, Ikeda also reports the observation of negative energy, which he calls the “most significant achievement in this study”, given its potential applications in the study of gravitational field and quantum field phenomena.
