Abstract
We report a resource-efficient scheme in which a single pump laser was used to achieve frequency conversion by Bragg-scattering four-wave mixing in a photonic crystal fiber. We demonstrate bidirectional conversion of coherent light between Sr+2P1/2→2D3/2 emission wavelength at 1092 nm and the telecommunication C band with conversion efficiencies of 4.2% and 37% for up- and down-conversion, respectively. We discuss how the scheme may be viably scaled to meet the temporal, spectral, and polarization stability requirements of a hybrid light-matter quantum network.
Highlights
Quantum networks provide a robust and scalable framework through which large-scale quantuminformation processing may be achieved [1]
In order to access the infrared telecommunication bands at which fiber links have minimum loss, photons may be coherently shifted by quantum frequency conversion (QFC) [7], usually by three- and four-wave mixing (TWM and FWM) processes
TWM processes lend themselves to large frequency shifts that can be driven by highpower laser systems at convenient wavelengths
Summary
Quantum networks provide a robust and scalable framework through which large-scale quantuminformation processing may be achieved [1]. In order to access the infrared telecommunication bands at which fiber links have minimum loss, photons may be coherently shifted by quantum frequency conversion (QFC) [7], usually by three- and four-wave mixing (TWM and FWM) processes. In this letter we present resource-efficient BS-FWM frequency conversion between the Sr+ emission wavelength at 1092 nm and the telecommunication C band.
