Mass-correction-induced enhancement of quantum correlations even beyond entanglement in the $e^{+} e^{-} \to J / I ¨ \to I^ (p I ¨ ^{-}) I^ˉ (p ˉ I ¨ ^{+})$ process at the BESIII experiment under memory effects

Elhabib Jaloum, Omar Bachain, Mohamed Amazioug +4

In this work, we derive the bipartite density matrix for the $e^{+} e^{-} \to J / I ¨ \to I^ (p I ¨ ^{-}) I^ˉ (p ˉ I ¨ ^{+})$ process at BESIII. We evaluate the impact of…

Optimal multiparameter quantum estimation in accelerating Unruh-DeWitt detectors

Omar Bachain, Elhabib Jaloum, Mohamed Amazioug +3

The quantum Fisher information matrix (QFIM) is central to multiparameter quantum metrology, dictating the attainable sensitivity via the quantum CramÃ©r-Rao bound. In this work, w…
