Squeezing is a nonlinear Gaussian operation that is a key component in the construction of other nonlinear Gaussian gates. In our implementation of the squeezing gate, the amount and the orientation of the squeezing can be controlled by an external driving signal with a 1-MHz operational bandwidth. This provides another way to view dynamic Gaussian processing. In particular, the gate can be immediately employed as the feedforward needed for the deterministic implementation of the quantum cubic phase gate, which is a key piece of universal quantum information processing.
