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.
