Summary

The Quantum Internet Research Group (QIRG) meeting featured four presentations: routing in quantum networks, timing regimes for quantum networks, an update on the multiplane architecture proposal for the quantum internet, and link-level multiplexing. Discussions covered terminology, protocol design, and practical considerations for building quantum networks.

Key Discussion Points

Routing in Quantum Networks: Explored routing strategies, analogous to classical networking, including proactive, reactive, virtual, and opportunistic routing. Swapping strategies (synchronous, asynchronous, opportunistic) and fidelity support (passive vs. active) were also discussed.
Timing Regimes for Quantum Networks: Identified critical timing regimes for quantum network components, including quantum optics (interferometric stabilization, photon overlap), hardware (detector timing, measurement basis selection, optical switch control), and software (event-driven tasks, application-level tasks, background tasks).
Multiplane Architecture for the Quantum Internet: Provided an update on a framework for the quantum internet, focusing on agility, sustainability, and playability. The proposed architecture leverages SDN principles and includes synthetic environments for testing.
Link Level Multiplexing Mechanism: Presented a multiplexing mechanism to resolve inconsistencies in resource allocation in multi-connection scenarios. The mechanism uses link allocation updates and barrier messages to align timing.

Decisions and Action Items

Michael and Siridi: Share the draft on advertising entanglement properties in OSPF/ISIS on the QIRG mailing list and in the chat.
Shoti: Share the URL for the link allocation update specification on the QIRG mailing list and in the chat.
Diego: Incorporate presentation feedback in the next draft of the multiplane architecture proposal.
Rodney and Wojtek: Coordinate to decide on the timing and location of the next QIRG meeting, focusing on Vancouver and Dublin. The mailing list will be updated.

Next Steps

The work on identifying what roles the different strata planes play will continue.
Further development of the synthetic environment for experimentation.
Vancouver and Dublin will be considered for future meetings, with Dublin being the stronger contender at present.
Feedback on the multiplane architecture proposal is requested from the QIRG mailing list.
