| contents | We show that one can exploit the representation of the Dicke state with magnetic quantum number $0$ in orthogonal bases to increase the probability of producing a large Kitten state or even a Cat state via dissipative one-axis twisting, resulting in a net increase in metrological sensitivity and robustness against white noise with respect to the initial state. The resulting states are also useful for quantum secret sharing. The success of the scheme is heralded by the rate of photoemissions. Unlike previous iterations, we have an important population of the larger Kitten states, which makes post-selecting trajectories for them feasible. |
