Friend @fucho80 in technology everything is possible. I tell you

In 2002 I was doing a course of Cisco networks at that time a classmate of that course was doing his thesis of electrical, the same was based on a mathematical algorithm that managed to create so that the capacity of 10 Cd that in At that time a CD had a storage capacity of 700 MB that algorithm that developed had the property that those 10 CDs could be stored on a floppy disk of just 1.44 MB
So I do not doubt that quantum supremacies is already working for a while now.

Note. my friend did not finish the course because a technology company recruited him.
