Is it true that more than two particles can be entangled in a quantum state?

Yes. Multiple studies and experimental results confirm that more than two particles can be entangled in quantum states, frequently demonstrated using three-photon or multi-atom Greenberger-Horne-Zeilinger (GHZ) states.

Verdict: SUPPORTED · 3 sources for, 0 against · Last checked 4 Aug 2026

The analysis

The claim is a well-established fact in quantum mechanics regarding multipartite entanglement. Multiple retrieved papers explicitly discuss, generate, or utilize multi-particle entangled states such as three-photon GHZ states and k-partite systems. Therefore, the verdict is SUPPORTED.
