Quantum energy teleportation is a quantum protocol proposed by Masahiro Hotta in 2008[1] allowing one party to put energy into the quantum vacuum, then send information to another party that lets them extract the energy from the vacuum.
In 2023, zero temperature quantum energy teleportation was observed and recorded by Kazuki Ikeda for the first-time across microscopic distances using IBM superconducting computers that are used for quantum computing.[2][3] Although teleportation of quantum information was achieved in the 1990s and has progressed since then, this is not the same as quantum energy teleportation. Also, although some popular magazine headlines say this process appears to "pull energy out of nothing," the articles explain this is not the case. Creating energy out of nothing is not possible according to the current understanding of the laws of physics.[4][5]
