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