(a) the probability of absorbing a photon within the lifetime (N) of the superabsorbing E2LS comprising N atoms, compared with that of N individual atoms over the same duration. The relative advantage is linear in N as expected, and the coloured shading indicates the quantum advantage. (b) lifetime of the E2LS for growing N relative to the four atoms case . Note that the decrease in lifetime corresponds to an increasing time resolution of a superabsorbing photon detector: after initialization the system is receptive to a photon of the requisite frequency only during this time window. (c) absorption rate at the midpoint of the Dicke ladder (blue) and for N individual absorbers (red). The clearly visible N² scaling that is typical of superradiant pulses also applies to the absorption rate.
