Note added.-Recently, two related papers have been published: one that investigates mixed steady states of dissipatively coupled Kerr-resonator arrays, which correspond to the ground states of a frustrated antiferromagnet [63] ; and another that studies the generation and detection of two-mode cat states in dissipatively coupled parametric oscillators [64] for the particular case N = 2 only.
