Researchers have made advancements in the field of quantum computing. Researchers made another significant advancement when they effectively applied the ideas of quantum physics to move data in light patterns without actually moving the image.
Researchers have shown that they can transport information in quantum form at the highest dimensionality ever measured. This especially emphasizes the use of a configuration modeled after teleportation, in which data is transferred electronically rather than physically between the two communicating parties.
Photon entanglement and nonlinear optical detection
A nonlinear optical detector and entangled photons were employed in a unique technique by the researchers.
By using this method, they were able to overlap a photon that was sent by the recipient with the data that was to be sent, making it appear at the recipient’s end as though it had been teleported there instead of requiring the data to physically travel between the sender and the recipient.
According to the statement, the researchers demonstrated a state-of-the-art development in 15 dimensions, opening the door for future expansion and high-capacity quantum network connections.
An international team from ICFO – The Institute of Photonic Sciences, Spain, and the University of the Witwatersrand, Johannesburg, carried out the research under the direction of Professor Andrew Forbes of Wits University.
Qubits sent from one satellite to another
Information acquisition over long distances requires quantum communication, which has been demonstrated by satellites exchanging two-dimensional states known as qubits.
While this might seem adequate in comparison to classical communication, in which bits are sent one at a time and encoded as 1s for a signal and 0s for no signal, researchers pointed out that quantum optics expands their capabilities.
They cleared the path for scientists to securely represent more complex systems, such as a complete facial image or a unique fingerprint, all in a single transmission, and to use a wider range of information symbols.
Put simply, researchers showed how to combine quantum processes with the ability to control unique light patterns. This enabled them to employ cutting-edge quantum states in a fresh manner.
According to Dr. Adam Vallés of ICFO (Barcelona), this experiment shows the feasibility of the process, motivating further advances in the nonlinear optics community by pushing the limits toward a full quantum implementation.
“We have to be cautious now, as this configuration could not prevent a cheating sender from keeping better copies of the information to be teleported, which means we could end up with many Mr Spock clones in the Star Trek world if that is what Scotty wanted.”
He continued, saying, “From a practical point of view, the configuration that we currently demonstrate can already be used to establish a high-dimensional secure channel for quantum communications between two parties, provided that the protocol does not need to be fed with single photons, as would be the case for quantum repeaters.”
