We investigate cluster states of qubits with respect to their non-local properties. We demonstrate that a Greenberger-Horne-Zeilinger (GHZ) argument holds for any cluster state: more precisely, it holds for any partial, thence mixed, state of a small number of connected qubits (five, in the case of one-dimensional lattices). In addition, we derive a new Bell inequality that is maximally violated by the 4-qubit cluster state and is not violated by the 4-qubit GHZ state.

  1. Calibrated hypergraph states: II calibrated hypergraph state construction and applications

    quant-ph 2025-01 conditional novelty 6.0 of 10

    Calibrated hypergraph states over Galois rings generalize weighted hypergraph states, are stabilizer and locally maximally entangleable, and reduce to the weighted class in the qubit case only.

  2. Calibrated hypergraph states: I calibrated hypergraph and multi qudit state monads

    quant-ph 2025-01 conditional novelty 6.0 of 10

    Calibrated hypergraphs and multi-qudit states are shown to form graded Ω monads, providing a categorical foundation for a broad generalization of hypergraph states.
