Interaction-free generation of entanglement | | Hiroo Azuma

4 Apr 2003 | | Journal: | Phys. Rev. A 68, 022320 (2003) DOI: 10.1103/PhysRevA.68.022320 | | Subject: | quant-ph | | Abstract: | In this paper, we study how to generate entanglement by interaction-free measurement. Using Kwiat et al.’s interferometer, we construct a two-qubit quantum gate that changes a particle’s trajectory according to the other particle’s trajectory. We propose methods for generating the Bell state from an electron and a positron and from a pair of photons by this gate. We also show that using this gate, we can carry out the Bell measurement with the probability of 3/4 at the maximum and execute a controlled-NOT operation by the method proposed by Gottesman and Chuang with the probability of 9/16 at the maximum. We estimate the success probability for generating the Bell state by our procedure under imperfect interaction. | | Source: | arXiv, quant-ph/0304031 | | Services: | Forum | Review | PDF | Favorites | |
