6 Feb 2007 | Abstract: | By employing at recent proposal (R. Filip, P. Marek and U.L. Andersen, Phys. Rev. A {f 71}, 042308 (2005)), we experimentally demonstrate a high-fidelity, deterministic and universal squeezing transformation of a quantum state. The approach circumvents a direct interaction between a strong pump and the quantum state, but relies only on linear optics, homodyne detection, feedforward and an ancillary squeezed vacuum state. We demonstrate three different squeezing operations with attained fidelities of 94%, 89% and 78%. | Source: | arXiv, quant-ph/0702049 | Services: | Forum | Review | PDF | Favorites |
