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.
IQOQI ViennaAustrian Academy of SciencesPhysical Review LettersTeleportation still needs an ordinary message
Quantum teleportation transfers a quantum state through a protocol that combines shared entanglement, a measurement and an ordinary message. The receiver uses that message to reconstruct the state. A person or object does not make a science-fiction journey, and the communication step prevents the protocol from delivering a usable message faster than light. [1]
Anton Zeilinger and his collaborators helped make these ideas experimental. The 2022 Nobel Prize in Physics recognised Zeilinger, Alain Aspect and John Clauser for work on entangled photons, Bell inequality violations and quantum information science. The recognition joins several contributions and experimental traditions; it does not make one person the sole inventor of quantum teleportation. [2][3]
For the next teleportation headline, follow the resources: where was entanglement prepared, what was measured and what ordinary information reached the receiver? Those questions help explain how the result works and what it can accomplish. They also keep a memorable name connected to the wider collaboration behind the experiment. [1][3]
Keep asking: What does the receiver need before a transferred quantum state becomes usable?

The work behind the recognition
Work, in context- Year not documented
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.
