Abstract
As electronic devices get smaller, quantum effects begin to appear. These effects may one day be useful in quantum computational devices, but to take full advantage of them quantum coherence must be maintained for long times at practical temperatures. In his Perspective, Sham discusses results presented in the same issue by Kikkawa et al. that reveal long-duration spin memory at room temperature in a semiconductor material. The findings open the way to further study of spin coherence in condensed matter systems.
