Is Quantum Teleportation of Energy Possible?

Largecover There is an increasing awareness among the world's scientific community that the properties of the universe are best described not by the laws that govern matter but by the laws that govern information, which appears to be true for the quantum world, is true for special relativity, and is now being explored for general relativity.

Using the same quantum principles that enable the teleportation of information, a proposal by Japanese physicist Masahiro Hotta of Tohoku University shows how it may be possible to teleport energy. By exploiting the quantum energy fluctuations in entangled particles, physicists may be able to inject energy in one particle, and extract it in another particle located light-years away. The proposal could lead to new developments in energy distribution, as well as a better understanding of the relationship between quantum information and quantum energy.

Previously, physicists have demonstrated how to teleport the quantum states of several different entities, including photons, atoms, and ions. Researchers predict that the principles of teleportation could also extend to molecules, viruses, and other more complex objects. Over the past year, physicists have also been exploring quantum energy teleportation, and Hotta’s latest paper builds on these studies.

As in previous examples of teleportation, the actual particles aren’t teleported since they’re basically identical at the quantum level. Rather, the information they carry is the important part. For this reason, physicists can simply send the information within a particle and not the particle itself. A receiving particle accepts the information from a sending particle, taking on the identity of the sending particle.

Hotta’s paper marks the first example of the energy-entanglement relation for the smallest kind of quantum energy teleportation model. As he explains, the findings could enable scientists to explore the foundations of physics: specifically, the relationship between quantum information and quantum energy.
