Engineering quantum correlations between light modes at different frequency would open new avenues for quantum networks and sensing. Here, the authors propose and demonstrate a way for obtaining high-purity strongly entangled continuous variable stat

Real-time quantum feedback control can be used to cool quantum systems to their motional ground states, but this has been so far achieved via classical probe fields. Here the authors report feedback cooling of a mechanical oscillator using a squeezed

We report continuous variable entanglement between light modes of different colors (852nm and 1064nm). Entanglement is demonstrated from radio-frequency down to the acoustic frequency range. The high-purity state violates the separability limit by -7

Stimulated Raman spectroscopy has become a powerful tool to study the spatio-dynamics of molecular bonds with high sensitivity, resolution, and speed. However, the sensitivity and speed of stimulated Raman spectroscopy are ultimately limited by the s

We report on double-resonant highly efficient sum-frequency generation in the blue range. The system consists of a 10-mm-long periodically poled KTP crystal placed in a double-resonant bow-tie cavity and pumped by a fiber laser at 1064.5 nm and a Ti:
