Achieving multifrequency mode entanglement with ultraslow multiwave mixing.
We propose a scheme to achieve the entanglement of N photon modes (frequency modes) with perfectly efficient ultraslow multiwave mixing in a cold atomic medium. In addition, the method provides an efficient approach to realizing frequency tunability.
