Abstract We use complex network theory to study a class of photonic continuous variable quantum states that present both multipartite entanglement and non-Gaussian statistics. consider the intermediate scale several dozens modes at which such systems are already hard characterize. In particular, built from an initial imprinted cluster state created via Gaussian entangling operations according s...

Abstract Detecting the structure of spacetime with quantum technologies has always been one frontier topics relativistic information. Here, we analytically study generation and redistribution Gaussian entanglement scalar fields in an expanding spacetime. We consider a two-mode squeezed state via amplification channel that corresponds to time-evolution from asymptotic past future. Therefore, dyn...
