This research demonstrates that star topology networks with more than three nodes can maintain non-local quantum correlations indefinitely, even under relativistic acceleration where chain networks fail. The findings reveal a dual role for the Unruh effect in protecting entanglement and highlight how network structure fundamentally governs resilience against decoherence in high-speed environments. While these insights offer theoretical guidance for designing robust future communication protocols, practical implementation over vast distances or with imperfect detectors remains an open challenge.

Liaoning Normal Team Finds Star Networks Resist Relativity’s Decoherence

Quantum ZeitgeistAugust 25, 20263 min read

Chain networks lose all nonlocal connections under acceleration, but star networks with more than three nodes maintain them indefinitely. This unexpected resilience demonstrates how topology governs behaviour in relativistic environments, challenging previous understandings of decoherence. A minimal three-node star network even displays a ‘death-birth’ cycle as speed increases.

An irreversible sudden death of non-locality occurs under relativistic motion, but star networks exhibit strong resilience against relativistic decoherence. A minimal star network containing three peripheral nodes exhibits a remarkable sudden death-sudden birth transition of network nonlocality as acceleration increases. This reentrant behaviour reveals a dual role for the Unruh effect; it can both suppress…
