superconducting nanowires

Superconducting nanowires are extremely thin wires made from materials that conduct electricity without resistance when cooled to very low temperatures. Because they have no resistance, they can carry electrical current with perfect efficiency, meaning no energy is lost as heat. These nanowires are often just a few nanometers wide—much thinner than a human hair—and are used in advanced technologies like sensitive detectors, quantum computing, and medical imaging. Their unique properties arise from quantum effects at tiny scales, enabling revolutionary advancements in electronics and measurement precision.
