Benchmarking suite for Quantum Network Applications
Quantum networks with a small number of quantum nodes are presently being developed in research labs around the world. In QIA, we have developed the world’s first full stack quantum network system, which allows programming of quantum network applications in high level software. A high level SDK for this has also been released as part of Quantum Network Explorer, presently running on a simulation backend for the public. Going to this website, you can find both a graphical interface to explore running simple tasks on a Quantum Network, as well as an SDK with examples to play with.
In this internship you will take part in developing a test suite to test the workings of such a full stack system. Along the way we will also learn more about the requirements of implementing specific applications on quantum hardware. A starting point for this are several applications (such as blind quantum computation) for which software code is already written and available to use in this project. The code can be run on a simulated quantum network that can be configured with some parameters (e.g. memory lifetime of the qubits, quality of the entanglement, …). Running each such application does give some confidence in the workings of this system of course, and allows us to extract features such as the success probability of the application. One question would be to understand how informative different applications are about the workings of the system. To learn more about Quantum Networks, we recommend a general overview article  to start with. While it is possible to conduct the project with an abstract understanding of the quality of entanglement and the memory lifetime, we recommend expanding your quantum knowledge with the notion of (1) the fidelity of quantum states – this determines the quality of entanglement (2) quantum teleportation, and (3) a model for the memory lifetime of qubits. You can read about this in e.g. [4,5], and a summary will be provided at the start of this project.
In addition, the project leaves room to explore new applications for which no code samples are yet available, or to come up with interesting other tests. Some ideas for such tests already exist that can be explored or expanded as part of this project.
Right now there are no test suites for quantum network applications available. The project leaves room forr you to work with QIA researchers to publicly release a test suite, and contribute to publishable research together with QIA researchers. Test suites for quantum computing systems are not suited for testing quantum network systems, since quantum network applications need often very different things than quantum computing applications. However, papers written in the domain of quantum computing may give some ideas of what such research can lead do [1,2].
