Quantum Coherence Limits Entanglement Spread in Complex Systems

Quantum Zeitgeist Archived Mar 31, 2026 ✓ Full text saved

For years, quantifying the link between quantum complexity and measurable properties like entanglement remained an open challenge. Now, mathematical relationships demonstrate how the spreading of quantum states in Krylov space is fundamentally limited by existing entanglement and coherence. These bounds clarify how complexity relates to core quantum resources, offering a new framework for characterising quantum systems.
