Quantum Computing Update, from Dylan Distasio
These are two extremely important papers in Nature that have big implications longer term. Both of them solved a problem using quantum computing that classical computing cannot currently address even at the supercomputer level.
Obviously, no impact to cryptocurrencies yet, but it is something to keep in mind for the long game in terms of potential disrupters to encryption in general:
