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.
