DESCRIPTION:Speaker: Lucas Sylvester Winter\nhosted by Julian Léonard and 
 Maksym Serbyn\nAbstract: Abstract:Standard Dicke superradiance produces a 
 collective burst of radiation but no entanglement. Using finite-size quant
 um-jump simulations\, we show that adding local Rydberg blockade between a
 toms generates extensive mixed-state entanglement while preserving superra
 diance. This enables superradiantly accelerated preparation of correlated 
 dark states on a timescale $\\propto (\\log N)/N$\, supported by an early-
 time analytical solution and numerical simulations. The physical mechanism
  is Hilbert-space fragmentation of the Dicke ladder into an exponentially 
 branching decay tree\, giving rise to a hierarchy of correlated dark state
 s. We propose an experimental realization using existing cavity-coupled Ry
 dberg atom tweezer arrays and identify a simple stationary-state entanglem
 ent witness. More broadly\, our results point to Rydberg-blockaded collect
 ive decay as a general framework for engineering entangled dark states
