Quantum computers? First photonic router demonstrated

(1/1)

tamim_saif:
Scientists have demonstrated for the first time a photonic router -- a quantum device based on a single atom that enables routing of single photons by single photons. This achievement is another step toward overcoming the difficulties in building quantum computers.

Illustration of the photonic router the Weizmann Institute scientists created. At the center is the single atom (orange) that routes photons (yellow) in different directions.

In near future, will it be possible to produce photonic microprocessor, where instead of electron movement, logical calculation will be done based on photon movement?

Are they going to replace the copper/ gold connector with tiny optical fiber lines on a PCB?
