Sydney, June 29: Researchers have hit upon a new and simpler way of manipulating light to enable quicker, more secure data transfer.
The discovery is based on existing optical technology, but uses it in such a way that fewer components and light beams are required, said research leader Jiri Janousek, from the Australian National University (ANU).
Janousek said this discovery about mode manipulation in light meant that only one light source and one receiver is required to generate optical entanglement, meaning that this approach could be scaled up to convey many more information channels.
"There are only 10 labs in the world that would be able to do this kind of research, and we were the first to find a solution to this particular problem," Janousek said, according to an ANU release.
Their findings were published in the journal Nature Photonics.
