Advanced the foundations and experimental control of photon entanglement, including multipartite quantum states and entanglement swapping between photons that had never interacted directly.
Austrian Academy of SciencesPhysical Review LettersZeilinger helped make entanglement an experimentally usable resource as well as a test of quantum foundations. His work ranges from the theoretical structure of multipartite correlations to laboratory protocols that connect initially separate entangled pairs. These contributions matter for quantum information because a network must create and distribute correlations, not merely send ordinary signals. His inclusion reflects that foundational and experimental record, with the GHZ framework and entanglement-swapping experiment attributed to their collaborators.

The Greenberger–Horne–Zeilinger framework
With Daniel Greenberger and Michael Horne, Zeilinger developed the framework for GHZ states. These multipartite entangled states provided a way to explore correlations involving more than two quantum systems and their implications for quantum foundations.
Co-developer of the GHZ framework with Daniel Greenberger and Michael Horne.

Entangling photons that never interacted
Zeilinger, Jian-Wei Pan, Dik Bouwmeester and Harald Weinfurter demonstrated entanglement swapping. A joint measurement on one photon from each of two pairs projected the remaining photons into an entangled state, although those photons had not interacted.
Co-author with Jian-Wei Pan, Dik Bouwmeester and Harald Weinfurter.
