Not really. If that turns out to be true (nothing is guaranteed yet), the processes described are pretty straightforward and don’t require any super-advanced tech to be reproduced. Full-scale production could be rolled out in mere years. That would become beneficial for stuff like MRIs or electric cars as soon as production starts.

After that, my guess would be that some large-scale energy infrastructure projects, for example, could be completed in about a decade.

You still need a magnet-superconductor pair for quantum locking and magnetic levitation. This is called the Meissner effect and it seems like it has been confirmed for this material. Here’s a video showing an example of such a system.

Before, the best way to scale this up might’ve been to make permanent magnet rails and run a superconductor train along those rails, but that would have been totally infeasible and inapplicable in real life, since building rails out of permanent magnets is expensive and dangerous, and the train would need to house a really large superconductor chilled to liquid nitrogen temperatures. You couldn’t have built a track out of superconductors irl because good luck keeping those at the temperatures required for superconductivity to kick in.

If this material turns out to actually work as claimed and to be producible at scale, you can switch those and make an electromagnetic train that travels along superconductor tracks. Which is way easier, cheaper and much more doable in general.

But the earth’s magnetic field is extremely weak, and even the tiniest pieces of superconductors are unable to lock with it. So no, it does not allow for trackless levitation.

But a cool new train system design becomes possible though!

Superconducting materials will expel an induced magnetic field as it creates internal fields that exactly cancel out the induced one. You'd still need some sort of "rails" to created the induced field and to move it to generate forward motion.
