Outline of Final Research Achievements

We have solved key problems in the development and deployment of a true quantum Internet. Most important among these, we have designed and simulated a mechanism for building entanglement end-to-end along a path through the quantum Internet, crossing boundaries between different types of quantum networks. All key mechanisms have been designed, most importantly the recursive path setup algorithm and software management of distributed quantum states. The complete Internet simulation remains in development. We developed and simulated a "quantum sneakernet" mechanism, for building entanglement using entangled quantum states moved via container ship. We simulated quantum network coding using mixed quantum states as a "middleware" means of optimizing use of a Quantum Internet, and established that penalties on end-to-end fidelity are acceptable.
