The project "Multi-Photon Entanglement and Quantum Teleportation" concerns a series of experimental and theoretical investigations on multi-photon entangled states and the applications, for example, quantum teleportation. The objective of this research is to probe the foundations of quantum;theory of entanglement and its fundamental roles in quantum computing and quantum information processing. This research will definitely benefit many scientific and engineering discipline applications. This report is for the first year investigation of a long term basic research program. The efforts of the first year research are very important for the achievement of our long term goal. Based on the successful results of the first year research, a novel teleportation experiment which has the ability to provide a true "100% teleportation" shall be conducted in the second year.

The article on quantum teleportation (January p5), which said that this phenomenon had been demonstrated for the first time by a group from the University of Innsbruck, is not quite correct. The first successful quantum teleportation experiment was in fact performed by our group in Rome. Our paper, "Experimental realisation of teleporting an unknown pure quantum state via dual classical and Einstein-Podolsky-Rosen channels" (D Boschi et al. 1998 Phys. Rev. Iett. 80 1121), was submitted in July of last year and published last month. The teleportation paper by the Innsbruck group, led by Anton Zeilinger, was submitted on 16 October of last year and published in December (Bouwmeester et al. 1997 Nature390 575).

Quantum teleportation is one of the most striking consequence of quantum mechanics and is defined as the transmission and reconstruction of an unknown quantum state over arbitrary distances. This concept was introduced for the first time in 1993 by Charles Bennett and coworkers, it has then been experimentally demonstrated by several groups under different conditions of distance, amount of particles and even with feed forward. After 20 years from its first realization, this contribution reviews the experimental implementations realized at the Quantum Optics Group of the University of Rome La Sapienza.
