Scientists have transmitted quantum and conventional internet data through the same fiber-optic channel, meaning a future quantum internet could theoretically use existing infrastructure. When you ...

A new type of optical fiber filled with nothing but thin air has been found to be particularly effective for carrying out quantum key distribution (QKD), a security protocol that is in principle ...

Researchers have shown how ultrastable optical signals from optical clocks can be transmitted across tens of kilometers of deployed multicore fiber carrying telecommunications data. Nazanin Hoghooghi, ...

Scientists in China claim to have developed a new type of ultra-thin optical fiber that could improve brain imaging and boost high-speed communications. This fiber, which runs on an optical neural ...
