The Quantum Computing Cybersecurity Preparedness Act, which President Biden signed just before Christmas, essentially codified his administration's efforts to examine and catalog the government information technology (IT) systems that would soon be vulnerable to quantum computers. This is a crucial first action. It is a difficult task to switch the entire federal IT infrastructure over to new cryptographic systems, and today's action is needed to work out the implementation issues. Federal officials then need to take the initiative and actively share what they discover. For those who are unaware, quantum computing is a promising technology that has not yet reached its full potential. It also poses a risk to many of the most popular types of cryptography-based computer security because of its distinctive capacity to avoid time-consuming mathematics. Future incarnations of quantum computers might easily turn into a security problem even though they aren't now powerful enough to pose a threat. The majority of secure communications, banking transactions, and other applications would be helpless.
