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.
Extends PID to quantum domain with applications showing unique info must be zero in erasure-correctable QEC subsets and redundant info central to Zurek decoherence.
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.
Reports experimental generation of remote Bell entanglement between two giant atoms with fidelity 0.89 using driven-dissipative stabilization and in-situ frequency tuning.
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.
Simulations identify anisotropic ground stations, multi-inclination LEO orbits, and multi-party service policies as key to achieving concurrent global quantum connectivity with acceptable latency and link strength.
