Deterministic Generation of Remote Entanglement using Shaped Single Photons in Circuit Quantum Electrodynamics
ORAL
Abstract
Sharing information coherently in a quantum network is the foundation of quantum communication and distributed quantum information processing. Here, we discuss our progress toward implementing a deterministic quantum state transfer and remote entanglement protocol in a circuit QED architecture. We embed a superconducting transmon-type three level system in a transmission line resonator at two spatially separated nodes. We generate an itinerant shaped microwave photon based on a microwave drive induced second-order process [1] and transmit it via a coaxial line [2]. Emitting and absorbing the single photon with high fidelity ideally achieves coherent qubit state transfer or remote entanglement generation. Our experiments, therefore, suggest a path toward realizing all-microwave quantum networks based on deterministic interactions between individual nodes.
