Continuous-variables graph state generation and reconstruction
If you have a question about this talk, please contact Paul Skrzypczyk.
Gaussian graph states represent the basic resource for measurement-based quantum computation with continuous variables. I will present two approaches for obtaining them. The first  involves a family of Hamiltonians whose ground states are Gaussian graph states, thus opening the way for their adiabatic preparation in physical settings beyond the standard optical ones. Regarding the second approach  I will present a general scheme, applying both to discrete- and continuous-variable systems, for sequential one-way quantum computation, where both the generation of the graph state and its consumption by measurements are carried out simultaneously. Finally, I will introduce a minimal scheme to reconstruct those states (and any arbitrary state) in the case of quantum networks composed of interacting continuous variables .
