Will quantum computers disrupt critical infrastructure?


Quantum computers will be able to crack existing encryption and threaten critical infrastructure.

“Anything that's protected by something that's vulnerable becomes fair game for people that have access to quantum relevant computers,” says Jon France, chief information security officer at non-profit cybersecurity organization ISC2. Greg Wetmore, vice president for software development at security firm Entrust, says if such devices could emerge in the next decade, technology leaders need to ask, “What data in your organization is valuable for that period of time?” While the impact of the millennium bug might have been minimal in the first days of 2000, that's because an immense amount of work had gone into fixing it ahead of a known deadline, says François Dupressoir, associate professor in cryptography at the University of Bristol.
