Composition of quantum network (IMAGE)
Caption
(a) The quantum network is fully connected by five subnets (A, B, C, D and E are represented by red, orange, green, blue, and black, respectively). The dotted lines between the subnets (10 links with different colors) are the correlated time-energy photon pairs between the subnets. (b) Every subnet (such as subnet A) is equipped with a 1×3 beam splitter and a delay controlling module, which splits a frequency-correlated entangled photon pair (red and blue signs) and sends them to three users randomly.
