  Squeezing is a nonlinear Gaussian operation that is the key component in
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 1 MHz operational bandwidth. This
opens a brand new area of dynamic Gaussian processing. In particular, the gate
can be immediately employed as the feed-forward needed for the deterministic
implementation of the quantum cubic gate, which is a key piece of universal
quantum information processing.
