From entanglement to a quantum network
Bell tests, teleportation and connected quantum systems. Four sourced contributions to read in sequence.
- STOP 1 OF 4 · Test the correlations
Alain Aspect
1982 · Bell tests with changing measurement settings
With Jean Dalibard and Gérard Roger, Aspect published a Bell-inequality experiment using time-varying analyzers. The work sharpened experimental tests of entanglement and the distinction between quantum correlations and local classical explanations. It was part of a sequence of experiments, with explicit experimental limitations.
Coauthored experiment by Alain Aspect, Jean Dalibard and Gérard Roger.

Charles H. Bennett
1993 · Quantum teleportation
Bennett, Brassard and four coauthors proposed transferring an unknown quantum state using shared entanglement, a measurement and classical communication. The protocol established a reusable quantum-information primitive and does not permit faster-than-light signaling or the copying of an arbitrary unknown state.
Coauthored protocol by Charles H. Bennett, Gilles Brassard, Claude Crépeau, Richard Jozsa, Asher Peres and William K. Wootters.

Ronald Hanson
2021 · A network with multiple quantum nodes
Hanson’s QuTech biography records his group’s demonstration of entanglement in a multi-node quantum network. This extended the laboratory’s work from individual links toward coordinated operations among connected quantum processors.
Research-group contribution documented by QuTech; multi-node entanglement is attributed to the team.

Stephanie Wehner
2025 · QNodeOS for quantum network applications
Wehner co-authored the paper introducing QNodeOS, an operating-system architecture for running high-level applications on quantum network nodes. The team demonstrated delegated computation between diamond-based nodes and a driver for a trapped-ion node, separating application software from hardware-specific control.
Co-author of the paper reporting QNodeOS and its collaborative demonstrations.
