High-speed quantum networking by ship
Here we show that error-corrected quantum memories installed in cargo containers and carried by ship could provide a flexible and scalable connection between local networks, enabling low-latency, high-fidelity quantum communication across global distances. With recent demonstrations of quantum technology with sufficient fidelity to enable topological error correction, implementation of the necessary quantum memories is within reach, and effective bandwidth will increase with improvements in fabrication. Thus, our architecture provides a new approach to quantum networking that avoids many of the technological requirements of undersea quantum repeaters, providing an alternate path to a worldwide Quantum Internet.
