Deterministic entanglement - 2018

We have succeeded in generating quantum entanglement between two quantum chips faster than the entanglement is lost. Entanglement – once referred to by Einstein as “spooky action” – forms the link that will provide a future quantum internet its power and fundamental security. Via a novel smart entanglement protocol and careful protection of the entanglement, we were able to deliver such a quantum link ‘on demand’. This opens the door to connect multiple quantum nodes and create the very first quantum network in the world. The results were published on 14 June in Nature.


Spookiness on demand!
