• Scientists may have found the holy grail of quantum computing A rare metal alloy may be the long-sought key to ultra-fast quantum computers that waste virtually no energy. • Scientists believe so called triplet superconductors could open the door to the most energy efficient technologies ever developed. • “A triplet superconductor is high on the wish list of many physicists working in the field of solid state physics,” said Professor Jacob Linder. • Linder is a physicist at the Norwegian University of Science and Technology’s (NTNU’ Department of Physics, where he works at QuSpin – a research centre that brings together some of the university’s leading researchers. • “Materials that are triplet superconductors are a kind of ‘holy grail’ in quantum technology, and more specifically quantum computing,” explained Linder. • Researchers around the world are eager to confirm the existence of such materials.
Article Summaries:
- Scientists at the Norwegian University of Science and Technology report that the alloy niobium‑rhenium (NbRe) may exhibit triplet superconductivity-a rare state where electrons pair with parallel spins. If confirmed, this material could conduct both electrical and spin currents without resistance, potentially stabilizing quantum bits and drastically reducing the energy required for quantum computing. The discovery, detailed in a Physical Review Letters paper, could serve as a cornerstone for next‑generation quantum and spintronic devices, addressing current challenges of instability and power consumption in quantum technology.
