| Abstract(in English) | Determining the states of signals accurately is a challenge for quantum information science. In order to deal with the issue, we need to use the best possible quantum measurements to suppress the influence of quantum noise. Although BWSRM is a well-known quantum measurement that is useful in theory, much less study has been done on its details, such as how much a Hilbert space is coverd. In order to utilize BWSRM more effectively, we should understand it more deeply. In this study, the geometric representation of BWSRM for pure state signals is presented and considered. |
