21 Dec 1999 | | Journal: | Phys. Rev. A 62 (2000) 042302 | | Subject: | quant-ph | | Affiliation: | University of Science and Technology of China | | Abstract: | We propose a probabilistic quantum cloning scheme using Greenberger-Horne-Zeilinger states, Bell basis measurements, single-qubit unitary operations and generalized measurements, all of which are within the reach of current technology. Compared to another possible scheme via Tele-CNOT gate [D. Gottesman and I. L. Chuang, Nature 402, 390 (1999)], the present scheme may be used in experiment to clone the states of one particle to those of two different particles with higher probability and less GHZ resources. | | Source: | arXiv, quant-ph/0001081 | | Services: | Forum | Review | PDF | Favorites | |
