Over the past twenty years, the field of quantum computing has progressed from the investigation of individual quantum systems towards the implementation of many-qubit processors. Distributing information processing over a quantum network consisting of many nodes that communicate via itinerant photons is one potential framework for achieving modular and extensible quantum computation. Systems of superconducting qubits strongly coupled to a continuum of photonic modes in 1D coplanar waveguides, described by the formalism known as waveguide Quantum Electrodynamics (wQED), are emerging as a promising platform for quantum communication. In this work, we develop a quantum module comprised of superconducting qubits strongly coupled to a 1D waveguide that can bidirectionally emit and absorb propagating microwave photons on-demand. These modules can be tiled in series along a waveguide to form an all-to-all, extensible quantum network.

Experiments utilizing quantum optics have progressed rapidly in last few decades, particularly in the context of quantum computation, simulation, and communication. Early work in this field focused on implementations of cavity quantum electrodynamics (QED), where atoms, either natural or artificial, are strongly coupled to the confined photonic modes of cavities. However, in recent years, achieving strong coupling between atoms and itinerant photons has also gained significant interest for its applications in quantum networking. To this end, many atomic platforms are attempting to realize the waveguide QED architecture: atoms that interact with the continua of propagating photonic modes within a waveguide.
