Possibility to generate any Gaussian cluster state by a multimode squeezing transformation
Stefano Zippilli, David Vitali · Physical Review A · 2020
Gaussian cluster states are ideal infinitely squeezed states. In practice it is possible to construct only approximated version of them with finite squeezing. Here we show how to determine the specific multimode squeezing transformation, which generates a faithful approximation of any given Gaussian cluster state.
