PME Special Seminar: A Three-Node Quantum Network of Diamond Qubits
- Wednesday, June 2, 2021 10:00am - 11:00am
Matteo Pompili, QuTech, TU Delft
- A large-scale network of quantum nodes connected by long-distance entanglement will unlock fundamentally new technologies, such as secure communication, distributed quantum computing, and simulation.
Defect centers in diamond are promising candidates to act as nodes of such a network, owing to their optical interface for entanglement generation and multiple long-lived qubits. By connecting three remote quantum nodes based on the Nitrogen Vacancy (NV) center in diamond, we established a key platform to test, develop and explore multinode quantum network protocols . In this talk, Pompili will discuss the main technological advancements that enabled the generation of multipartite entanglement across the nodes of our quantum network and the execution of entanglement swapping to achieve any-to-any connectivity without the use of postselection.
Finally, he will present updates on his effort to increase the capabilities of the three nodes and run a quantum network application.
