WebDicke superradiance, has been reported experimentally [3, 4]. In contrast, the R = 0, M = 0 state does not decay in the Dicke limit; it is a subradiant state. In practice, subradiant states do emit, but slower than the atomic spontaneous emission rate. Subradiant states have attracted much interest in quantum memory and quantum information [5]. Webdospin basis (also known as the Dicke state basis [44]). The projected squeezed state is produced through a sequence of control operations including initialization, rotation, spin squeezing [45], quantum measurement, and postselection. Experimentally, the main technical challenge is carrying out a projective measurement of the collective spin ...
