Building a circuit around a tiny diamond beam offers a way to keep more of the light that future quantum computers and networks could use. Building a quantum network often comes down to a stubborn materials problem. Diamond can host quantum emitters, tiny systems that produce light signals, while other materials are better suited to [...]
Researchers from the United States and the Republic of Korea have developed a new approach to connect diamonds to titanium dioxide photonic circuits, aiming to reduce the loss of light in quantum networks.
