A research team from the Australian National University has developed a new method for transmitting data with light, which can lead to super-fast quantum computers and teleportation technology, local media reported Monday.
Australian scientists devised the new technique for generating quantum entanglement in beams of light using only two parts, according to a report by Australian Associated Press on Monday.
"Usually, when you want to generate entanglement you need a lot of sources of light and a lot of receivers but we found a way to use only one source and one receiver to generate and measure entanglement," research team leader Jiri Janousek was quoted as saying in the report.
Quantum entanglement is a process in which two objects are linked together in such a way that any changes to the properties of one can be measured from the other regardless of the distance between them.
This process of linking particles has existed for a few years but Janousek said this new method allows it to be achieved in a much simpler way.
It involves entangling two specially modified beams of light so that changes to the amplitude or phase of one beam can be measured with the other.
"This finding is one more piece in the puzzle towards the future realization of quantum computers, which would be many times faster and more powerful than existing computers," he said.
