Entangled quantum communication is advancing rapidly, with laboratory and
metropolitan testbeds under development, but to date there is no unifying
Quantum Internet architecture. We propose a Quantum Internet architecture
centered around the Quantum Recursive Network Architecture (QRNA), using
RuleSet-based connections established using a two-pass connection setup.
Scalability and internetworking (for both technological and administrative
boundaries) are achieved using recursion in naming and connection control. In
the near term, this architecture will support end-to-end, two-party
entanglement on minimal hardware, and it will extend smoothly to multi-party
entanglement and the use of quantum error correction on advanced hardware in
the future. For a network internal gateway protocol, we recommend (but do not
require) qDijkstra with seconds per Bell pair as link cost for routing; the
external gateway protocol is designed to build recursively. The strength of our
architecture is shown by assessing extensibility and demonstrating how robust
protocol operation can be confirmed using the RuleSet paradigm.Comment: 17 pages, 7 numbered figure
