Scientists may have spotted a long-sought triplet superconductor — a material that can transmit both electricity and electron spin with zero resistance. That ability could dramatically stabilize quantum computers while slashing their energy use. Early experiments suggest the alloy NbRe behaves unlike any conventional superconductor. If verified, it could become a cornerstone of next-generation quantum and spintronic technology.

essentially a conductor for "spin currents"

"The fact that triplet superconductors have spin has an important consequence. We can now transport not only electrical currents but also spin currents with absolutely zero resistance," explained Linder.

That ability could make it possible to transmit information using spin without any energy loss. In turn, extremely fast computers could operate using almost no electricity at all.

I don't know what any of this means... but cool!

Still need massive amounts of energy to cool them down to superconducting temperatures

Well, if we had these aboard the International Space Station or a spaceship, we could simply choose to crank the heat down in the computer room. Might actually save energy in that case.

Dream big!
