We present multiparty entanglement purification protocols that are capable of purifying arbitrary graph states directly. We develop recurrence and breeding protocols and compare our methods with strategies based on bipartite entanglement purification in static and communication scenarios. We find that direct multiparty purification is of advantage with respect to achievable yields and minimal required fidelity in static scenarios, and with respect to obtainable fidelity in the case of noisy operations in both scenarios.

  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.
