Traditional encryption methods have long been vulnerable to quantum computers, but two new analyses suggest a capable enough machine may be built much sooner than previously thought

Bluvstein thinks a capable enough machine won’t be ready until the end of the decade. “There’s a lot of progress that needs to be made, but it’s starting to become something that people can really imagine building,” he says.

…

NIST has chosen several PQC algorithms that could become the security standard in a future filled with practical quantum computers, and the US federal government is aiming to migrate to using them by 2035. But Moody says organisations should begin their transition as soon as possible. “These papers reinforce the idea that the window for migration is finite and the time to act is now,” he says.

    Traditional encryption methods have long been vulnerable to quantum computers

    I assume that’s in the same way that my chimney has long been vulnerable to Santa Claus.

      I think it is pretty widely accepted in cybersecurity that traditional encryption methods are vulnerable to quantum computers?

      This isn’t really a “cold fusion” thing.

      The entire desire to build a Quantum Computer is related to solving problems a traditional computer would take ages to do. There has been meaningful steady progress towards it too, though no one seriously expects results tomorrow.
