Timing quantum emission: Coherence, superradiance, and entanglement in order

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.
