“…Continuous variable (CV) QC, where information is encoded in the amplitude and phase quadratures of photonic harmonic oscillators, can be realized deterministically and unconditionally [3,25,26]. The CV cluster state is a basic resource for one-way CV QC [3] and quantum networks [27,28]. Recently, large-scale CV cluster states in time the domain [29,30] and with frequency comb [31,32] have been prepared experimentally, and provide sufficient quantum resources for one-way CV QC.…”
