Spin-flavor entanglement in Lambda_b to Lambda D decays supplies a method to extract the CKM weak phase gamma with uncertainty scaling as 1 over the Wootters concurrence.
Transverse polarization in e+e- collisions generates maximally entangled fermion pairs in QED processes and boosts entanglement in electroweak and Bhabha scattering.
