The commonly used teleportation-based interfaces between light and matter are very sensitive to noise of matter systems and also to the optical in-coupling and out-coupling losses. These imperfections produce classical noise in the teleportation interface, which significantly limits the transmission of quantum states. We propose robust quantum interfaces between weakly coupled continuous variables of light and matter. The state transfer introduces only pure loss, without any additional classical noise, despite a presence of in-coupling and out-coupling optical losses. These interfaces qualitatively overcome commonly used interfaces based on quantum teleportation.
