The quantum computer has the potential to revolutionize the 21st century, solving problems so massively complex th today’s computers would take a century to solve. But a single quantum computer is still no match for the more than billion classical computers currently in use. But, as with classical computers, quantum computers need a quantum internet, and researchers at The Australian National University may have found the perfect way to store quantum data long enough to share the information around a next-generation internet which promises to be impervious to hacking.
“The effort to build a quantum computer is often described as the space race of the 21st century,” said Dr Sellars, who is the Program Manager in the Centre for Quantum Computation and Communication Technology (CQC2T) at ANU. “Our work will allow us to build a global network to connect quantum computers.”

The work, published in Nature Physics, addresses a crucial challenge that has eluded researchers worldwide. Lead researcher Associate Professor Matthew Sellars from the ANU Research School of Physics and Engineering said the improved storage was an important part of a viable quantum internet.

The team used a rare earth element, called erbium, in a crystal ...
