My understanding is that quantum computing has been taken into account for some modern cryptography. And that memory-hard cryptography basically defeats quantum computing solutions. There are a few methods, but one of them is just very long keys, it’s trivial to make a cryptographic key longer.
So sure, you could defeat some of that with a machine operating with 1024 entangled qbits, (which is… oh man… not an easy task), in which case, wow, congratulations. But what if I increase my key length to 100k? It might take an extra 3 seconds to check the key and log in, but it’ll take an extra 25 years for quantum computing to catch up.
