Teleportation may seem relegated to “Star Trek” reruns and sci-fi flicks, but a team of physicists at the University of Queensland have discovered technology that may soon make this novel mode of transportation a reality.
In a study published in this month’s issue of Nature journal, the scientists outlined how they succeeded in transmitting a single atom from one location to another within an electronic chip. Researcher Dr. Arkady Fedorov noted that this result marked the first time the team had achieved quantum teleportation, and the results may later be imitated in larger networks.
Said Fedorov, “This is a process by which quantum information can be transmitted from one place to another without sending a physical carrier of information. In this process the information just appears at the destination, almost like teleportation used in the famous science fiction series Star Trek.”
He also said, “Eventually this technology will be used to create more powerful devices.”
According to Fedorov, their teleportation experiment used a type of correlation called entanglement, which was shared from a sender to a receiver. The laws of quantum mechanics make this system work.
From the published study:
At the current state of the art, quantum bits (qubits) are fabricated, initialized, controlled, read out and coupled to each other in simple circuits. This enables the realization of basic logic gates, the creation of complex entangled states, and the demonstration of algorithms or error correction.
Fedorov explained, “What makes our work interesting is the system uses a circuit, much like modern computer chips. In our system the quantum information is stored in artificial structures called quantum bits, and you can even see them with your bare eyes.”
He also said, “In our Superconducting Quantum Devices laboratory at UQ we are using this technology to further enhance our knowledge about the quantum nature. Eventually this technology will be used to create more powerful devices.”
