![]() ![]() Raman noise is suppressed with a free-space cavity filter and the majority of components are fiber-integrated, enabling the conversion of single photons with high signal-to-noise ratio and overall efficiency up to 4%, about two orders of magnitude higher than achieved in previous works. By splitting horizontal and vertical polarization components and up-converting each separately within a stabilized interferometer, the authors demonstrate the preservation of polarization entanglement upon conversion. In this paper, the authors report a sum-frequency generation (SFG) interface from 1560 nm in the telecoms C band to 795 nm, a convenient wavelength for storage in quantum memories. The frequency conversion of single photons has crucial roles to play in forming hybrid light-matter networks, primarily as a transducer linking shorter wavelengths typically used for processing and storage in atomic and solid-state systems with the fiber telecommunications bands, as well as enabling devices that operate at different wavelengths to share quantum information. Large-scale quantum networks have the potential to revolutionize computation and information transfer. ![]() Note: Author names will be searched in the keywords field, also, but that may find papers where the person is mentioned, rather than papers they authored.Use a comma to separate multiple people: J Smith, RL Jones, Macarthur.Use these formats for best results: Smith or J Smith.For best results, use the separate Authors field to search for author names.Use quotation marks " " around specific phrases where you want the entire phrase only.Question mark (?) - Example: "gr?y" retrieves documents containing "grey" or "gray".Asterisk ( * ) - Example: "elect*" retrieves documents containing "electron," "electronic," and "electricity". ![]() Improve efficiency in your search by using wildcards.Example: (photons AND downconversion) - pump.Example: (diode OR solid-state) AND laser.Note the Boolean sign must be in upper-case. Separate search groups with parentheses and Booleans. ![]() Keep it simple - don't use too many different parameters. ![]()
