So… when can we finally can throw a bit of quantum entanglement into the recipe?
A step toward the quantum Internet
The first elementary quantum network based on interfaces between single atoms and photons has been developedby scientists at the Max Planck Institute of Quantum Optics (MPQ).
It consists of two coupled single-atom nodes that communicate quantum information via coherent, reversible exchange of single photons.
Besides giving insights into fundamental questions in physics, the finding could also have applications in secure communication and the simulation of complex many-body systems They could also lead to distributed quantum computing.
“This approach to quantum networking is particularly promising because it provides a clear perspective for scalability,” says Professor Gerhard Rempe, director at the Max Planck Institute of Quantum Optics and head of the Quantum Dynamics division. […]
