Rice-sized laser

Rice-sized laser, powered one electron at a time, bodes well for quantum computing Date: January 15, 2015 Source: Princeton University 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. The device demonstrates …

Quantum Teleportation

A new distance record has been set in the strange world of quantum teleportation. In a recent experiment, the quantum state (the direction it was spinning) of a light particle instantly traveled 15.5 miles (25 kilometers) across an optical fiber, becoming the farthest successful quantum teleportation feat yet. Advances in quantum teleportation could lead to better Internet and communication security, …
