Bidirectional Generation of Itinerant Microwave Photons with Waveguide Quantum Electrodynamics (Part 2)

ORAL

Abstract

A node that can communicate quantum information between processors is a necessary component of a general architecture for a large-scale, fully-connected quantum network. Quantum information is generally communicated between nodes via propagating (itinerant) photons, or via a bus coupler that coherently couples adjacent nodes. Protocols involving itinerant photons require lossy components such as microwave circulators, which limit the communication fidelity and fix the direction of communication between nodes. The hardware requirements for protocols involving bus couplers limit node connectivity. In this work, we present progress towards realizing a device that can bidirectionally emit and absorb itinerant microwave photons. The directionality is enabled by the interference between the emission of superconducting qubits in a waveguide quantum electrodynamics architecture. We also present progress towards implementing communication between two nodes by emitting and capturing a photon. This device can be used as the building block for an all-to-all quantum network.
