A maglev train hovers above its track. A doctor uses an MRI scanner to detect disease. Fast digital circuits send superfast, clear signals from one source to another. These technologies are possible thanks to superconductors. Superconductors are materials where electrons can move without any resistance. But today's superconductors don’t work unless they are cooled to well below room temperature. Now researchers are using quantum physics on a quest to find superconductors that will work at room temperature to make them easier to use.
