Quantum Frequency Conversion of Single Photons from a Tin-Vacancy Center in Diamond

Posted by klaurent Delft

Kavli Affiliate: Ronald Hanson | First 5 Authors: Julia M. Brevoord, Julia M. Brevoord, , , | Summary: Diamond tin-vacancy (SnV) centers are promising candidates for building quantum network nodes. However, their native photon emission at 619 nm is incompatible with metropolitan-scale networks operating at low-loss telecom wavelengths. To address this, we demonstrate highly efficient, […]
