The first ever Demonstration of Energy Teleportation

Not only can information traverse from one point in the universe to another without traversing the intervening space, but teleportation represents the capability to transmit quantum information across the universe without the need to traverse the space in between. This process involves transmitting the complete information describing an individual particle to another location, causing the second particle to assume all the attributes of the first.

The second particle becomes physically identical to the first, essentially becoming the original particle, albeit situated in a different part of the universe. This concept, known as teleportation, was initially demonstrated in the 1990s. Presently, teleportation is a routine occurrence in quantum optics laboratories and stands as a fundamental technology underpinning the gradual development of the quantum internet.

Energy Transmission

However, it serves another purpose. In the 2000s, Masahiro Hotta, a Japanese physicist at Tohoku University, extended the concept by proposing that if teleportation could transmit information, it should also have the capacity to transmit energy. Subsequently, he laid the theoretical groundwork for quantum energy teleportation.

Now, Kazuki Ikeda at Stony Brook University in New York state claims to have achieved the first-ever teleportation of energy using a conventional quantum computer. He asserts, “We report the first realization and observation of quantum energy teleportation on real quantum hardware,” emphasizing that the ability to teleport energy could profoundly impact the future of the quantum internet.

The fundamental concept behind quantum energy teleportation is rooted in the continuous fluctuations of energy within any quantum system. These inherent energy fluctuations at the quantum level can be leveraged for teleportation.

Hotta initially highlighted that measuring a portion of a quantum system inherently introduces energy into the system. In the quantum realm, this energy can then be extracted from a different part of the system without traversing the space in between. No net gain or loss of energy occurs; it is simply transferred.

Demonstrating this concept necessitates a collection of quantum particles that share the same quantum state and are thus entangled. While such entangled systems were challenging to obtain when Hotta first conceived the idea, Ikeda noted that recent years have seen the ready availability of systems of entangled particles, thanks to the advent of quantum computers.

IBM’s quantum computers, for instance, are based on superconducting qubits and are accessible via the internet. Ikeda formulated the quantum algorithm to implement Hotta’s idea and then utilized IBM’s quantum computer for its execution. He notes, “The results are consistent with the exact solution of the theory.”

Within IBM’s quantum computer, Ikeda achieved teleportation of energy over distances approximately the size of a computer chip. However, he asserts that now that the idea has been demonstrated, it should be immediately feasible to teleport energy over much greater distances.

Quantum Networking

He emphasizes that the technology to accomplish this is already in existence over current connections, such as a 158-kilometer link connecting Stony Brook University and Brookhaven National Laboratory. Looking ahead, Ikeda envisions the possibility of teleporting energy across a quantum internet, expected to materialize, most likely, in the 2030s.

According to Ikeda, this development will have far-reaching consequences. “The ability to transfer quantum energy over long distances will bring about a new revolution in quantum communication technology,” he declares.

He envisions a future where energy and information will be exchanged over the quantum internet, allowing traders to select the most economically advantageous sources. This, in turn, is expected to give rise to a novel field: quantum information economics, according to Ikeda.

However, achieving this vision involves several successive stages, with a crucial one being the demonstration that teleportation can effectively transmit substantial amounts of energy. Another intriguing aspect is exploring the extent to which energy teleportation differs from information teleportation and understanding the nuances that distinguish the two. This exploration is anticipated to shed light on the fundamental nature of the universe and the true roles played by information, energy, and other elemental components in shaping our reality.
