Abstract
Entanglement is an essential resource at the heart of quantum information processing and quantum metrology. Moreover, multimode entanglement is necessary for the fabrication of complex quantum networks, in which entanglement is distributed among several quantum modes. The nodes of the network are made from quantum modes, which are the fundamental information carriers, and these nodes are interconnected by a series of channels through which the information flows. Multimode entanglement is traditionally viewed as many-body correlations, in which the nodes are spatially separated and can be measured individually. In our multimode resource, all of the modes travel together within a single laser beam [1]. This co-propagation of modes enables us to construct on-demand quantum networks via arbitrary shaping within the measurement process.
