Researchers at the University of Science and Technology of China and other Chinese labs, with the collaboration of a lab in the US, have implemented a secure quantum protocol known as Measurement-Device-Independent Quantum Key Distribution (MDIQKD), suitable for practical networks and devices, over a distance of 404 km. The breakthrough, which doubles the previous MDIQKD record, opens the door to secure wide area quantum communication networks.
Hacked recently covered the efforts of the Chinese government to build unbreakable quantum communication networks. According to analysts, quantum communications networks are so expensive that they could have a “recentralizing effect,” enabling states to recover the ground that they have lost to decentralizing digital technologies. But what if ultra-secure quantum cryptography could be made available to everyone at low cost?
One year ago Hacked covered the race between the US and China to develop “military super-powers” by harnessing quantum science, and noted that Chinese scientists were developing quantum communication satellites that support unbreakable encryption. A few weeks ago, China launched its first quantum satellite.
A group of physicists in Australia’s capital city of Canberra are looking away from crypto-based mathematics encryption to work on encryption based on the laws of physics, or more specifically – quantum physics. This form of encryption is deemed ‘unbreakable’.
A group of physicists at the Australian National University (ANU) are hard at work with quantum cybersecurity solutions that potentially help develop ‘unbreakable encryption’.
The endeavor is borne from QuintessenceLabs, a company created in 2008 after ANU researchers discovered quantum physics to significantly improve encryption. Built out of ANU, the [...]
