| Title: | Quantum channel estimation and asymptotic bound | Authors: | Hayashi, M. | Issue Date: | 2010 | Citation: | Hayashi, M. (2010). Quantum channel estimation and asymptotic bound. Journal of Physics: Conference Series 233 : -. ScholarBank@NUS Repository. https://doi.org/10.1088/1742-6596/233/1/012016 | Abstract: | Quantum channel estimation in the one-parameter case is treated with the asymptotic setting. This problem sometimes has square speedup. A sufficient condition for this speedup is obtained. In this case, the existing results in Cramér-Rao approach seem to contradict the existing results in covariant approach. In order to resolve this problem, we introduce two kinds of asymptotic bounds. © 2010 IOP Publishing Ltd. | Source Title: | Journal of Physics: Conference Series | URI: | http://scholarbank.nus.edu.sg/handle/10635/126346 | ISSN: | 17426588 | DOI: | 10.1088/1742-6596/233/1/012016 |
