Category:Entanglement Distribution Network stage: Difference between revisions

The third network stage, entanglement distribution allows shared entanglement i.e. two nodes can be connected using [[Glossary#Entangled States|entanglement]]. It could be further used to share states between two nodes without physically transferring the qubits over quantum channels. Yet this feature cannot be completely put in use unless one can store quantum states which is only possible with quantum memory, not a technology accessible at this network stage. It includes all the prepare and measure network stage technologies along with sharing of entanglement between two nodes separated by some distance. This stage allows generation of multipartite entangled states, followed by immediate measurements. [https://en.wikipedia.org/wiki/Postselection Post-selection] on detection events when measuring qubits is prohibited. The main advantage over the previous stages ([[:Category:Trusted Repeater|Trusted Repeater]] and [[:Category:Prepare and Measure Network Stage|Prepare and Measure Network Stage]]) is that this stage allows the realization of device independent protocols, in which the quantum devices are
