This study dissects the temporal hierarchy of quantum phenomena in closely spaced emitters, establishing that relative coherence precedes correlated emission and entanglement peaks. The findings clarify the sequential emergence of these states, offering critical insights for optimizing quantum networks and scalable quantum computing architectures.

arXiv:2512.07055v2 Announce Type: replace Abstract: We investigate the short-term temporal dynamics of superradiance in closely spaced quantum emitters. Building on Dickes 1954 framework, we analyze the sequential emergence of coherence, superradiance, and entanglement, revealing a distinct temporal hierarchy in their extremal values: relative coherence develops first, followed by the peak of correlated emission, then minimal entanglement, and subsequently minimal spin-spin correlation is reached. These findings suggest that enhanced relative coherence precedes correlated emission, and when spin correlations are negligible, entanglement and correlated emission become linked in time.
