Sustainable Long-Distance Quantum Teleportation Achieved, Implications For Space Colonization

Physicists find a way to maintain quantum teleportation of information across a long distance. The discovery may allow for the development of a massively entangled “quantum internet” on Earth and in outer space. As well as providing an instantaneous, radiation free way of communicating.

The milestone was reached by a team of researchers at the Fermilab, US Department of Energy Office of Science national laboratory and other partners. It was published in PRX Quantum.

It represents the first sustainable long distance (44 kilometres of fiber) teleportation of photon qubits with an accuracy exceeding 90%. Further development may enable picture perfect transference of data in the form of quantum entangled particles of light (photon) which they call “qubits” in quantum computing.

Panagiotis Spentzouris, head of the Fermilab quantum science program and one of the paper’s co-authors. “This is a key achievement on the way to building a technology that will redefine how we conduct global communication.”

Being able to encode information in to entangled particles is one thing, but then to transport those particles across the fabric of space and time instantaneously? That is another huge achievement and sparks the beginning of a United States based quantum network in Chicago.

“With this demonstration we’re beginning to lay the foundation for the construction of a Chicago-area metropolitan quantum network,” Spentzouris said. The Chicagoland network, called the Illinois Express Quantum Network, is being designed by Fermilab in collaboration with Argonne National Laboratory, Caltech, Northwestern University and industry partners.

Although they highlight the implications of this discovery in quantum computing, that form of quantum teleportation need not necessarily apply to the development of AI or computation. Instead it could be used to erect a vast communication infrastructure in outer space. Who knows, eventually we may even come up with a way to evaporate and rematerialize larger objects using quantum teleportation.

Arguably, it is the most scientifically valid way for us to communicate across the entire solar system in the same amount of time that we’re used to here on Earth. If we can do that without any form of electromagnetic radiation (radio, wifi), and instead use quantum teleportation to send information it may be a lot better for our health in the long run.

With that being said – In the future, a communication infrastructure based off of quantum teleportation would allow for quicker development of interplanetary colonies through live-action cross-referencing of logistics and resource availability.

That way if anything unexpected comes up we can adjust our trade route to compensate for the event right away instead of waiting weeks months or years for the message to arrive, at which time it may be too late to mitigate damage to the economy. This form of network adaptability is exactly what we need for a complex system like interplanetary trade.
