| Research Abstract |
During the first year of the project, we have:
1. Selected several network topologies for further study, based on real-world network configurations extracted using the Rocketfuel tool. 2. Worked on the necessary simulator capabilities (work still in progress). 3. Developed state machine models for certain portions of the protocol stack. 4. Worked on methods for synchronizing distributed density matrices between network nodes. 5. Worked on the interface between classical application software and the quantum network. 6. Studied the requirements to successfully run large applications. Defined a taxonomy of timing regimes for chains of quantum repeaters
Some of these results are described in the book _Quantum Networking_, Rodney Van Meter, Wiley-ISTE, 2014.

Current Status of Research Progress
3: Progress in research has been slightly delayed.
Reason
The discussions of how to coordinate the concepts of distributed density matrices have resulted in more fundamental work than originally anticipated.
Documenting aspects of the overall network design is a critical step. Creating the book that documents these both serves as a guide for detailed technical work, and as a tool for bringing new researchers into the project. The time invested in creating the book will be recouped through faster development in years 2 & 3.

| Strategy for Future Research Activity |
During FY2014, we will:
1. Complete the rewrite of the basic repeater simulation functionality.
2. Implement the single-layer version of Dijkstra's algorithm for repeater networks.
3. Build the basic infrastructure for repeater emulation, instead of repeater simulation.

| Expenditure Plans for the Next FY Research Funding |
Projected travel expenses were lower during FYH25 than previously projected. Technical work was conducted in-house for a greater percentage of work than previously projected.
For the coming year, an additional part-time researcher is being added to the staff. Travel expenses will be substantial in the coming year as collaborations with the U.S. increase.
