Comment on “Controlling the dynamical evolution of quantum coherence and quantum correlations in e + e − → Λ Λ ¯ processes at BESIII”
Abstract
We comment on the recent analysis reported in [], where quantum coherence, entanglement, steering, and non-Markovian dynamics were investigated in the process e + e − → Λ Λ ¯ . While the mathematical framework employed in that work may be formally well defined, we argue that several physical assumptions underlying its interpretation require further clarification. In particular, the treatment of the produced hyperon-antihyperon pair as an open bipartite system evolving under correlated quantum channels does not appear to follow naturally from the physical properties of the process. Moreover, the operational meaning of quantum steering and non-Markovianity in this relativistic unstable-particle system remains unclear due to the absence of controllable local measurements, engineered environments, and experimentally accessible dynamical maps. We emphasize that quantum-information-inspired observables can provide useful characterizations of spin correlations in high-energy reactions when their operational interpretation and physical assumptions are carefully specified. Our purpose is therefore not to question the mathematical consistency of the analyzed formalism, but rather to clarify the physical limitations associated with its interpretation in the Λ Λ ¯ system.
