Computer security experts have sounded alarms that the power of quantum computers may make it possible to crack current advanced encryption standards (AES) that are used to protect highly sensitive data. The key vulnerability of current encryption standards — including both the 256-bit AES and the 3,072-bit RSA — lies not in their being uncrackable,
The National Institute of Standards and Technology has been working to ensure that public-key cryptosystems will not be hackable once large-scale quantum computers are built. Although the delivery timeline of a mature quantum computer is under debate, NIST has already begun to prepare IT security to be able to resist quantum computing. It plans to
IBM recently unveiled what it claimed was the world’s first commercial quantum computer. While the announcement of the Q System One wasn’t scientifically groundbreaking, the fact that IBM sees this as a commercial product that organisations (if not individuals) will want to use is an important breakthrough. IBM has taken a prototype technology that has
