The world needs better cyber security, more so now than ever because of the current threat posed by future quantum computers. A wealth of new techniques are emerging to meet the diverse needs of users. However, to fully appreciate the emerging competitive dynamics and government actions in this sector, we also have to understand the long-term technological revolution that many believe will one day lead to the creation of the Quantum Internet.
Recently updated advice on quantum security technologies from the UK NCSC is bluntly sceptical about the promised benefits of quantum key distribution. This seems at odds with the scramble of governments around the world to promote the development of quantum networking technologies. Who is right? Future large scale quantum computers will one day bring many…
The breadth of the UK national quantum technology programme is impressive. Four flavours of qubit technology were on display, but its not just quantum computing , cryptography, sensors and imaging were just as strongly represented. Now in its third year, the momentum really shows. Hand portable and chip scale devices that are at or near…
