We introduce a class of multiqubit quantum states which generalizes graph states. These states correspond to an underlying mathematical hypergraph, i.e. a graph where edges connecting more than two vertices are considered. We derive a generalised stabilizer formalism to describe this class of states. We introduce the notion of k-uniformity and show that this gives rise to classes of states which are inequivalent under the action of the local Pauli group. Finally we disclose a one-to-one correspondence with states employed in quantum algorithms, such as Deutsch-Jozsa's and Grover's.

  1. Genuine Multipartite Entanglement between Logical Qubits via Cross-Code Lattice Surgery

    quant-ph 2026-07 accept novelty 7.5 of 10

    Cross-code lattice surgery between surface and 3D colour codes yields certified logical GHZ and |CCZ> GME plus arbitrary logical rotations on a trapped-ion processor.

  2. Graph restricted tensors: building blocks for holographic networks

    quant-ph 2025-12 unverdicted novelty 7.0 of 10

    Graph-restricted tensors generalize 1-uniform states, dual-unitary operators and AME states, with exact analytic solutions for new examples motivated by holographic lattice models.

  3. Device-Independent Self-Testing of the Three-Qubit CCZ Hypergraph State

    quant-ph 2026-07 accept novelty 6.0 of 10

    The CCZ hypergraph state and its Pauli measurements can be device-independently self-tested from twenty correlators, and also from maximal violation of a specially constructed Bell inequality.

  4. Magic-protected entanglement and Clifford-irreducible structure in magic state space

    quant-ph 2026-07 conditional novelty 6.0 of 10

    Quantum states are classified by how much bipartite entanglement survives optimal simplification by classically easy Clifford operations, yielding a split into weakly protected T-magic and strongly protected W-magic regimes.

  5. 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.

  6. 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.

  7. Entanglement Certification $-$ From Theory to Experiment

    quant-ph 2019-06 unverdicted

    Reviews paradigmatic entanglement quantifiers and state-of-the-art detection/certification methods, with emphasis on assumptions about states and measurements.
