TL;DR: A generalization of the cluster-state model of quantum computation to continuous-variable systems, along with a proposal for an optical implementation using squeezed-light sources, linear optics, and homodyne detection, is described.

TL;DR: The traditional approaches to quantum information processing using either discrete or continuous variables can be combined in hybrid protocols for tasks including quantum teleportation, computation, entanglement distillation or Bell tests.

TL;DR: In this paper, the authors derived necessary conditions in terms of the variances of position and momentum linear combinations for all kinds of separability of a multiparty multimode continuous-variable state.

TL;DR: It is proved that there are universal states for which the offline squeezing per mode does not increase with the size of the cluster and the existence of universal continuous-variable resource states is found.

TL;DR: This work experimentally realizes fully deterministic quantum teleportation of photonic qubits without post-selection, and even for a relatively low level of the entanglement, qubits are teleported much more efficiently than in previous experiments, albeit post-selectively, and with a fidelity comparable to the previously reported values.
