The nation must address a significant future threat in the potential adversarial development and deployment of a quantum computer—a machine that extends the usual rules of computation via quantum physics. Such a deployment would potentially have grave impacts on the security of the United States and its citizens if the proper technical mitigations are not put in place. Now is the time to prepare—in four ways highlighted below—for the complex transition to post-quantum algorithms well before the advent of a quantum computer. Read More
