Published 70 SCI papers, of which three Phys.Rev.Lett, 7 Nucl.Phys.B. A review article (book chapter, Springer Publishing). Published articles are cited nearly 500 others.
From the beginning of this century, research focused on quantum computing and quantum information processing. The main work in this area are:
1. In the study of quantum cloning to obtain a series of results, which range from the stringer and the phase cloning research group first made in Italy, made more widely recognized, and was several experimental groups and in the optical system such as system implementation and validation of NMR ( articles are cited).
2. of the VBS state the nature of quantum entanglement, and that its existence and functions closely associated with the relationship.
3. In the quantum entanglement theory, quantum channel capacity, it is also making a series of results, which had first proposed the graded level of quantum entanglement concept.
