Physicists have designed a new method for transmitting big quantum data across long distances that requires far fewer resources than previous methods, bringing the implementation of long-distance big quantum data transmission closer to reality. The results may lead to the development of future quantum networks, such as a global-scale quantum internet.

The researchers, Michael Zwerger and coauthors at the University of Innsbruck, Austria, have published a paper on the new long-range quantum communication method in a recent issue of Physical Review Letters.

"The greatest significance of our work is that we provide an efficient and scalable scheme for long-distance quantum communication," Zwerger told Phys.org. "We believe that this will be an essential ingredient for a future quantum internet, where large amounts of quantum data will be transmitted. Most importantly, in contrast to previous proposals, the required resources (per transmitted qubit) at each repeater station do not scale with the distance, which makes the quantum data transmission more efficient."
