[$] How to be safe from quantum computing

Practical quantum computers have been ten years away for the last severaldecades. Now, however, it's beginning to look as though they will bepossible in just a few years. Recentresearch with obfuscated results demonstrated much lower memory requirements to factorECDSA keys on a quantum computer, withwork by other researchers in the open more than halving memory use comparedto the state of the art in 2023.At the same time, computermanufacturers areboasting quantum processors that retain viable superpositions over longer periods.Given how slowly software updates filter out to stable systems, it's worthlooking at what configuration changes and protocol updates are needed to be safefrom quantum computers now.
