Single-photon emitters quantum mechanically connect quantum bits (or qubits) between nodes in quantum networks. They are typically made by embedding rare-earth elements in optical fibers at extremely ...

New device emits photons in telecom fiber band from the start, so it avoids a separate converter that can waste photons.

Researchers have taken an important new step in advancing the performance of resonator fiber optic gyroscopes, a type of fiber optic sensor that senses rotation using only light. Because gyroscopes ...

Fibre optic switches for single mode and multimode fibres based on a micro-mechanical/micro-optical concept provide excellent performance parameters, high flexibility ...

Tubular laser beams can create what amount to fiber-optic cables made of thin air, researchers report in a study to appear in Physical Review X. Laser-heated air can efficiently transmit light signals ...

Researchers at the University of Southampton in England have produced optical fibers that can transfer data at 99.7% of the universe's speed limit: The speed of light. The researchers have used these ...

With the rise of quantum computers, the security of our existing communication systems is at risk. Quantum computers will be able to break many of the encryption methods used in current communication ...

Imagine a computer that does not rely only on electronics but uses light to perform tasks faster and more efficiently. A collaboration between two research teams from Tampere University in Finland and ...
