| Rice-sized laser, powered one electron at a time, bodes well for quantum computing Posted: 15 Jan 2015 11:23 AM PST Researchers have built a rice grain-sized microwave laser, or 'maser,' powered by single electrons that demonstrates the fundamental interactions between light and moving electrons. It is a major step toward building quantum-computing systems out of semiconductor materials.  |
| Improved interface for a quantum internet Posted: 15 Jan 2015 05:30 AM PST A quantum network requires efficient interfaces over which information can be transferred from matter to light and back. Physicists now show how this information transfer can be optimized by taking advantage of a collective quantum phenomenon.  |
