Demonstration of deterministic and high fidelity squeezing of quantum information
Abstract
By employing at recent proposal (R. Filip, P. Marek and U.L. Andersen, Phys. Rev. A 71, 042308 (2005) 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.
