1. A method, comprising:
separately storing, while maintaining quantum integrity, first, second, third, and fourth photons, wherein the first and second photons and the third and fourth photons are respective first and second entangled photon pairs;
triggering a synchronized retrieval of the stored first, second, third, and fourth photons such that the first photon stored in a first quantum memory is propagated to a first node, the second photon stored in a second quantum memory and the third photon stored in a third quantum memory are propagated to a second node, and the fourth photon stored in a fourth quantum memory is propagated to a third node;
simultaneously measuring quantum features of the second and third photons at the second node; and
creating a new entangled pair comprising the first and fourth photons at the first and third nodes, respectively.
