Kinematic Control and Dephasing Dynamics of Quantum Resources in $e^{+} e^{-} \to τ^{+} τ^{-}$

Elhabib Jaloum, Omar Bachain, Mohamed Amazioug +1

We characterize several quantum resources carried by the spins of the $τ^{+} τ^{-}$ pair produced in $e^{+} e^{-}$ annihilation. At the Belle-II energy, $\sqrt{s}=10.579\,\mathrm{GeV…

Multiparameter quantum estimation and entanglement in top--antitop quark production

Omar Bachain, Elhabib Jaloum, Mohamed Amazioug +1

We investigate the interplay between quantum correlations and multiparameter quantum estimation in top--antitop quark pair production through the gluon-fusion channel. Using the sp…

Characterizing quantum correlations and quantum teleportation in $g g \to t t ˉ$ and $q q ˉ \to t t ˉ$ processes under noisy channels

Elhabib Jaloum, Omar Bachain, Mohamed Amazioug +4

The measurement of top-quark spin correlations provides a key tool for probing its interactions with high precision. Owing to its extremely short lifetime ( $τ \sim 1 0^{- 25}$ s), the…

Dephasing Effects on the Dynamical Evolution of Quantum Correlations and Coherence in Neutrino Oscillations

Omar Bachain, Elhabib Jaloum, Mohamed Amazioug +4

Neutrino oscillations confirm the presence of mode entanglement, as each flavor eigenstate is composed of a coherent superposition of distinct mass eigenstates. In this work, we in…

Reply to Comment on "Controlling the Dynamical Evolution of Quantum Coherence and Quantum Correlations in $e^{+} e^{-} \to Λ Λ ˉ$ Processes at BESIII"

Elhabib Jaloum, Mohamed Amazioug

In the annihilation process $e^{+} e^{-} \to J / ψ \to Λ Λ ˉ$ via $J / ψ$ , the hyperon--antihyperon pair emerges from the same non-perturbative QCD hadronization process, where both spins d…

Mass-correction-induced enhancement of quantum correlations even beyond entanglement in the $e^{+} e^{-} \to J / ψ \to Λ (p π^{-}) Λ ˉ (p ˉ π^{+})$ 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 $e^{+} e^{-} \to J / ψ \to Λ (p π^{-}) Λ ˉ (p ˉ π^{+})$ process at BESIII. We evaluate the impact of mass…
