Noise analysis of single-mode Gaussian operations using continuous-variable cluster states

Alexander, Rafael N; Armstrong, Seiji; Ukai, Ryuji; Menicucci, Nicolas C


We consider measurement-based quantum computation that uses scalable continuous-variable cluster states with a one-dimensional topology. The physical resource, known here as the dual-rail quantum wire, can be generated using temporally multiplexed offline squeezing and linear optics or by using a single optical parametric oscillator. We focus on an important class of quantum gates, specifically Gaussian unitaries that act on single quantum modes (qumodes), which gives universal quantum...[Show more]
