  By employing at recent proposal (R. Filip, P. Marek and U.L. Andersen, Phys.
Rev. A {\bf 71}, 042308 (2005) \cite{Filip05.pra}), we experimentally
demonstrate a universal, deterministic and high-fidelity squeezing
transformation of an optical field. It relies only on linear optics, homodyne
detection, feedforward and an ancillary squeezed vacuum state, thus direct
interaction between a strong pump and the quantum state is circumvented. We
demonstrate three different squeezing levels for a coherent state input. This
scheme is highly suitable for the fault-tolerant squeezing transformation in a
continuous variable quantum computer.
