摘要：

A generalized Mach-Zehnder-type interferometer equipped with cross-Kerr elements is proposed to convert N-photon truncated single-mode quantum states into (N + 1)-mode single-photon states, which are suitable for further state manipulation by means of beamsplitter arrays and ON/OFF-detections, and vice versa. Applications to the realization of unitary and non-unitary transformations, quantum state reconstruction and quantum telemanipulation are studied.
