Researchers have developed a microscopic 3D-printed optical device that can efficiently combine light from dozens of small semiconductor lasers into a single multimode optical fiber with very low loss ...

A high-frequency wand may offer benefits for skin appearance, including reducing fine lines or wrinkles and acne. However, more research is necessary to support these potential benefits. Using a ...

Researchers use rare-earth ions to achieve the first-ever demonstration of entanglement multiplexing between individual memory qubits in a quantum network. Laying the groundwork for quantum ...

Laying the groundwork for quantum communication systems of the future, engineers at Caltech have demonstrated the successful operation of a quantum network of two nodes, each containing multiple ...
