The science of quantum information has arisen over the last two decades centered on the
manipulation of individual quanta of information, known as quantum bits or qubits. Quantum …

This topical review introduces the theoretical and experimental advances in continuous-
variable (CV)—ie qumode-based in lieu of qubit-based—large-scale, fault-tolerant quantum …

Scalability and coherence are two essential requirements for the experimental
implementation of quantum information and quantum computing. Here, we report a …

One-way quantum computing allows any quantum algorithm to be implemented easily using
just measurements. The difficult part is creating the universal resource, a cluster state, on …

Continuous-variable Gaussian cluster states are a potential resource for universal quantum
computation. They can be efficiently and unconditionally built from sources of squeezed light …

We provide a unified graphical calculus for all Gaussian pure states, including graph
transformation rules for all local and semilocal Gaussian unitary operations, as well as local …

An extensible experimental design for optical continuous-variable cluster states of arbitrary
size using four offline (vacuum) squeezers and six beam splitters is presented. This method …

Quasi-phase-matching is an important technique in nonlinear optics and is in widespread
use. It not only makes efficient frequency conversion possible, but also enables diverse …

An optical comb is shown to arise from a whispering gallery mode resonator pumped by two
optical frequencies. Two externally excited modes couple due to Kerr nonlinearity to initially …

Cluster states with higher-dimensional lattices that cannot be physically embedded in three-
dimensional space have important theoretical interest in quantum computation and quantum …
