A newly developed laser the size of a grain of rice could lead the way to advances in quantum computing, new research says.

A team from Princeton University used quantum dots - tiny bits of semiconductor material that act like single atoms - to build a so-called "maser," or tiny microwave laser that emits light at longer wavelengths than traditional lasers. What's more, the device only requires one-billionth the electric...
