An upper bound on concurrence is derived for fixed local polarizations in two-qubit systems, saturated by pure states in some cases, and applied to show reduced maximal entanglement in polarized q qbar pairs from parity-violating Z decays.
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.
