Humanity as we speak is truly incredible. And alien technology far more sophisticated, crazy!

So it sounds like the moiré pattern creates areas of high resistance and low resistance, and replaces the josephson junction is regular superconductors?

by twisting at precise angle.

Yeah, but how do you modify the angle of one layer in the Bilayer Graphene? Nanomachines? (Actually, that is a good idea)

you simply assemble the structure layer by layer with one layer slightly rotated

We use the rich toolkit of the semiconductor industry. For instance, we don't need to mechanically twist anything, we can grow the single layer crystals in place through CVD (chemical vapor deposition). This process grows a structure from a series of strategically placed "nucleation" sites by having atoms fall into place from a gas phase. We can then first grow the bottom layer and then change the gas flow conditions, shifting the place where the second lattice will nucleate. This will grow a second rotated layer.

​@@pseudolullus Is there a technique to dynamically tune the twist angle?

@@alexanderitartakovskii7202 yes but this means absolute fidelity and consistency in fabrication so you can alter these at creation by these small scales and ensure it all fits properly. this stuff requires precision at least for now.
