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"

Yeah, getting rid of heat is the main issue in space. Insulating against cold is trivial.

But the principle behind it is why vacuum insulated tumblers can hold ice/hot liquid for so long.
