Quantum entanglement is a cornerstone of quantum mechanics. While entanglement between confined electron pairs is well-studied, free-traveling electron pairs remain largely unexplored due to significant challenges in spin measurement. We hereby propose a novel theory-assisted quantum entanglement test for free-traveling electron-positron pairs through polarization correlation measurements. The...
The time evolution of the neutral B mesons determines key parameters in flavor physics. While their behavior is generally studied under the assumption of perfect quantum coherence, interactions with the surrounding environment can introduce decoherence. The influence of such environmental effects on neutral meson systems can be effectively described using the open quantum system framework....
