Abstract

Quantum entanglement is not only the fundamental feature of quantum physics, it is the key ingredient in quantum information protocols. In order to achieve large-scale quantum information processing, large-scale multi-partite entangled states are needed. To date, entangled states containing around 10 modes have been generated using atoms, ions, photons, and optical continuous-variable (CV) schemes. In the vast majority of CV experiments, each optical mode is distinguished from the other modes by its spatial location.
