Query: High-speed quantum networking by ship   Networked entanglement is an essential component for a plethora of quantum
computation and communication protocols. Direct transmission of quantum signals
over long distances is prevented by fibre attenuation and the no-cloning
theorem, motivating the development of quantum repeaters, designed to purify
entanglement, extending its range. Quantum repeaters have been demonstrated
over short distances, but error-corrected, global repeater networks with high
bandwidth require new technology. Here we show that error corrected quantum
memories installed in cargo containers and carried by ship can provide a
flexible connection between local networks, enabling low-latency, high-fidelity
quantum communication across global distances at higher bandwidths than
previously proposed. With demonstrations of technology with sufficient fidelity
to enable topological error-correction, implementation of the quantum memories
is within reach, and bandwidth increases with improvements in fabrication. Our
approach to quantum networking avoids technological restrictions of repeater
deployment, providing an alternate path to a worldwide Quantum Internet.
