Multiparticle generalization of entanglement swapping
Open accessAbstract
We generalize the procedure of entanglement swapping to obtain a scheme for manipulating entanglement in multiparticle systems. We describe how this scheme allows one to establish multiparticle entanglement between particles belonging to distant users in a communication network through a prior distribution of singlets followed by only local measurements. We show that this scheme can be regarded as a method of generating entangled states of many particles and compare it with existing schemes using simple quantum computational networks. We highlight the practical advantages of using a series of entanglement swappings during the distribution of entangled particles between two parties. Applications of multiparticle entangled states in cryptographic conferencing and in reading messages from more than one source through a single measurement are also described.

Once one is able to entangle two photons that never interacted, one can construct very many types of entanglement, which in turn can be utilized in many ways.
“Once one is able to entangle two photons that never interacted, one can construct very many types of entanglement (Zeilinger et al., 1997), which in turn can be utilized in many ways (Bose et al., 1998).”

When particle 1 is a member of an entangled pair, the teleportation leads to entanglement swapping.
“This is the case when, as already remarked by Bennett et al. (1993), particle 1 itself is a member of an entangled pair, ultimately leading to entanglement swapping ( Żukowski et al., 1993;Bose et al., 1998).”

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
