Quantum networks of quantum computers offer a promising way to build quantum supercomputing clusters, as well as enabling the quantum internet. In this talk, I will present our work on networking trapped-ion quantum computers.

There are many different physical systems used for quantum computing and for quantum networking; it is challenging to find systems that offer both high performance qubits and high performance networking. I will describe a scalable approach to networking trapped-ion quantum processors, and present results showing a network-link fidelity and rate comparable to the intra-processor operations, allowing the networking operation to be used as a practical computing primitive.
I will then present recent results that use this primitive quantum network to implement Device-Independent Quantum Key Distribution (DIQKD), taking advantage of the processor's local operations and quantum memory to securely distribute a secret key across the network.
