The US The National Institute of Standards and Technology (NIST) has risen to the challenge of finding the encryption we will need when quantum (or just really capable) computers are developed in the future. After a strenuous vetting period they found four contenders to work with:

However one of the contenders, the Supersingular Isogeny Key Encapsulation (SIKE) algorithm has been found to be wanting – after just one month. It would not be so bad if a modern super computer had broken the encryption, but researchers did it with a 2013 vintage, regular Intel Xeon, single core, CPU, so not much power at all.
