This research presents a novel pump-free architecture for generating microwave-optical Bell pairs, addressing a critical bottleneck in connecting superconducting quantum processors to optical networks. By leveraging teleportation-based transduction across various physical systems like color centers and atomic ensembles, the scheme achieves high-fidelity heralding rates without relying on complex optical pumping mechanisms. This advancement directly enhances the scalability and robustness of hybrid quantum communication infrastructures.
Pump-Free Microwave-Optical Bell Pair Generation for Teleportation-Based Quantum Transduction
arXiv:2609.16364v1 Announce Type: new Abstract: The coherent conversion between microwave and optical photons, known as quantum transduction, is critical for connecting superconducting processors to optical networks. Existing methods are limited by complications associated with optical pumping. We propose a pump-free microwave-optical Bell-pair source for teleportation-based transduction. Using a spin or atomic system resonantly coupled to optical and microwave cavities, the scheme generates loss-robust heralded Bell pairs. Across color centers, atomic ensembles, and phonon-mediated systems, this assembly achieves kilohertz-range heralding rates with high fidelity.
