Abstract: Practical implementations of quantum information networks require frequency conversion of individual photons. Approaches based on a molecular gas as the nonlinear medium cover a wide range of the optical spectrum and promise high efficiency at negligible background. We present polarization-preserving frequency conversion in a hydrogen-loaded hollow core fiber using continuous-wave pump fields. We demonstrate conversion efficiency at the level of a few per mille, discuss various limitations and loss mechanisms, and present a route to increase conversion efficiency to near unity.

Low-noise quantum frequency conversion in a monolithic cavity with bulk periodically poled potassium titanyl phosphate [0.0]
Nitrogen-vacancy centers in diamond are a leading candidate to form the nodes of a quantum network. We demonstrate a new platform for efficient low-noise quantum frequency conversion based on a monolithic bulk ppKTP cavity. By resonantly enhancing the power of an off-the-shelf pump laser, we achieve an internal conversion efficiency of $(72.3pm 0.4)%$ while generating only $(110pm 4) mbox kHz/nm$ noise at the target wavelength.

High-efficiency microwave-optical quantum transduction based on a cavity electro-optic superconducting system with long coherence time [52.77024349608834]
Frequency conversion between microwave and optical photons is a key enabling technology to create links between superconducting quantum processors. We propose a microwave-optical platform based on long-coherence-time superconducting radio-frequency (SRF) cavities. We show that the fidelity of heralded entanglement generation between two remote quantum systems is enhanced by the low microwave losses.
