New proposal for efficient and low-noise quantum frequency conversion

We have recently published a new approach for realizing quantum frequency conversion across the very large spectral gap between the visible and telecommunications wavelength bands. 

This work, led by Xiyuan Lu, is in Optics Letters, and describes how third-order sum and difference frequency generation in microresonators can be a compelling approach for quantum frequency conversion.
