First demonstration of energy teleportation

Teleportation is the capacity to transport quantum information from one location in the universe to another without having to go across space. By transmitting all of the information characterizing a single particle to another, that second particle acquires all of the attributes of the first.

It is physically identical to the first particle and, in some ways, becomes the first particle, although in a different portion of the universe. As a result, the term “teleportation” was coined in the 1990s.

Teleportation is becoming a common occurrence in quantum optics labs and is a key technology behind the slowly emerging quantum internet.

Energy transger

However, it serves another purpose. In the 2000s, Masahiro Hotta of Tohoku University, a Japanese physicist, proposed that since teleportation can transport information, it should also be able to transfer energy. He then went on to provide the theoretical foundation for quantum energy teleportation.

Kazuki Ikeda of Stony Brook University in upstate New York claims to have used an ordinary quantum computer to transfer energy for the first time. “We describe the first realization and observation of quantum energy teleportation on genuine quantum hardware,” he adds, adding that the capacity to teleport energy might have far-reaching consequences for the future quantum internet.

The fundamental concept underlying quantum energy teleportation is that the energy of every quantum system is continually shifting. These inherent oscillations in energy can be used at the quantum level.

Hotta first pointed out that measuring a component of a quantum system necessarily introduces energy into the system. This energy can then be withdrawn from another section of the system in the quantum realm without the energy travelling across the space in between. There is no gain or loss of energy; it is just conveyed.

To demonstrate this concept, a group of quantum particles must be in the same quantum state and hence entangled.

These were difficult to come by when Hotta was creating his concepts. Ikeda, on the other hand, remarked that entangled particle systems have become widely available in recent years as a result of the introduction of quantum computers.

Indeed, IBM’s quantum computers are built on superconducting qubits and can be accessed via the Internet. Ikeda simply created the quantum algorithm that implemented Hotta’s notion and then ran it on IBM’s quantum computer. “The results coincide with the theory’s exact solution,” he says.

Ikeda was only able to transport energy over distances around the size of a computer chip using IBM’s quantum computer. However, he claims that after establishing the concept, it should be feasible to teleport energy considerably further out.

Quantum networks

He points out that the technology to do so already exists, such as a 158-kilometer link between Stony Brook University and Brookhaven National Laboratory. Furthermore, when a quantum internet becomes accessible, which is expected in the 2030s, Ikeda believes it will be feasible to teleport energy.

He believes it will have far-reaching consequences. “The capacity to communicate quantum energy across large distances will usher in a new era of quantum communication technology,” Ikeda adds.

He anticipates energy and information being transferred across the quantum internet, with merchants determining the most cost-effective location. According to him, this will result in a new science of quantum information economics.

Of course, numerous steps must be taken along the way, the most important of which is demonstrating that teleportation can transmit useful amounts of energy. Another intriguing subject is how and to what degree energy teleportation differs from information teleportation. This should assist us distinguish the underlying nature of the cosmos from the genuine function of information, energy, and other primitives in our reality.
