The interplay between non-stabilizerness and entanglement in random states is a very rich arena of study for the understanding of quantum advantage and complexity. In this work, we tackle the problem of such interplay in random pure quantum states. We show that while there is a strong dependence between entanglement and magic, they are, surprisingly, perfectly uncorrelated. We compute the expectation value of non-stabilizerness given the Schmidt spectrum (and thus entanglement). At a first approximation, entanglement determines the average magic on the Schmidt orbit. However, there is a finer structure in the average magic distinguishing different orbits where the flatness of entanglement spectrum is involved.

  1. Quantum Computational Resources and Conformal Field Theory: Unifying Spins, Bosons, and Fermions

    quant-ph 2026-07 accept novelty 8.0

    A unified Magic Rényi Entropy measure for spins, bosons, and fermions is shown to have a universal critical contribution determined by the Affleck-Ludwig boundary entropy.

  2. Magic without a phase: phase-independent stabilizer R\'enyi entropy in gluon scattering

    hep-th 2026-07 conditional novelty 7.0

    A phase-averaged stabilizer Rényi entropy is introduced for tree-level gluon scattering, with color-independent phase-independent magic that is larger in 3→2 than 2→2 and has a soft-limit lower bound in 2→3.

  3. Analytical Landscape of Maximal Magic for Two-Qutrit States and Beyond

    quant-ph 2026-07 conditional novelty 7.0

    Maximal stabilizer Rényi entropy for two-qutrit states is ln(81/17), achieved at 18 degenerate maxima; a general prime-d formula ln[d⁴/(2d²−1)] is conjectured and verified for d=2,3,5.

  4. Operational interpretation of the Stabilizer Entropy

    quant-ph 2025-07 unverdicted novelty 7.0

    The stabilizer Rényi entropy governs the exponential rate at which Clifford orbits become indistinguishable from Haar-random states and sets the optimal distinguishability from stabilizer states in property testing.

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

    quant-ph 2026-07 conditional novelty 6.0

    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.

  6. Long-range nonstabilizerness of topologically encoded states from mutual information

    quant-ph 2026-05 unverdicted novelty 6.0

    Mutual information between non-contractible regions on the torus fully classifies long-range nonstabilizerness for toric-code states but leaves a finite subset undetected in the doubled-Fibonacci string-net model.

  7. A trace distance-based geometric analysis of the stabilizer polytope for few-qubit systems
