摘要：

We propose a practical scheme for deterministically teleporting an arbitrary multipartite state, either product or entangled, using the Faraday rotation of the photonic polarization. Our scheme, based on the input-output process of single-photon pulses regarding cavities, works in low-Q cavities and only involves virtual excitation of atoms, which is insensitive to both cavity decay and atomic spontaneous emission. Besides, the Bell-state measurement is accomplished by the Faraday rotation plus product-state measurements, which could greatly reduce the experimental difficulty in realizing the Bell-state measurement by the CNOT operation.
