Towards an Era of Quantum Internet

In a significant breakthrough, engineers at the California Institute of Technology have demonstrated that atoms in optical cavities could lead to the creation of quantum internet- a system of interconnected quantum computers over a quantum network.

Optical Cavity and Quantum Network

• In order to be functionally viable, a quantum network needs to transmit information between two points without altering the quantum properties of the information being transmitted.
• To this end, the researchers constructed a nano-photonic optical cavity, a beam of about 10 microns length with periodic nano-patterning, sculpted from a piece of crystal. They then identified a rare-earth ytterbium ion in ....
