For product and X-form separable noise, exact Bell-mixing thresholds for entanglement and teleportation advantage are derived as 'absorption capacities' mapped by lambda = C/(1+C).
Pure-state BNMR is an intrinsic function of the nonzero Schmidt spectrum via dimension reduction, yielding quadratic perturbation response, Haar-random profiles localized at symmetric cuts, and closed forms for rank-2 states.
Semi-leptonic h→VV* decays retain an effective two-qutrit quantum description under NLO QCD and electroweak corrections, unlike the fully leptonic h→4ℓ channel.
A resource estimation framework for distributed fault-tolerant quantum computers based on lattice surgery identifies feasible hardware configurations for eight applications across thousands of setups, showing that architecture design must be guided by resource analysis for scalability.
Double selection distillation statistics alone suffice to estimate Bell-diagonal parameters of undistilled and post-processed states, outperforming prior distillation-based estimators in resource use.
Non-Markovian dephasing revives and protects quantum resources in polarized hyperon pairs, with a stable hierarchy of coherence over discord over entanglement across BESIII channels.
Proposes a heterogeneous quantum repeater network architecture using recursive designs and RuleSets with a new bridging building block, but states that full-scale resource trade-off analysis remains future work.
Three-spin interactions enable maximal concurrence near multicritical points and sustain entanglement for intra-phase quenches in a central spin model.
Extends Fano bounds to sufficiency of low conditional entropy and defines a quantum entanglement task for infinite-dimensional systems with bounds via maximal singlet fraction of finite-dimensional approximations.
A graph-based method is proposed to study entanglement entropy in CSS quantum codes, with illustrations on toric codes and quantum LDPC codes showing scaling behavior.
The claimed φ-only exact dynamics are invalid: Eqs. (7)-(8) do not imply Eq. (10), and the partial trace in Appendix B omits the |0001⟩ and |0010⟩ components.
