| 英文摘要 | Quantum phase distribution is expressed in terms of action-angle Wigner distribution function. It turns out to coincide with the limit case of Pegg-Barnett theory. This discrete phase space approach, in which some concepts such as quantum phase operator are not needed, can express phase-related quantities in a unified way. The expectation values and variances of cos theta and sin theta are the same as those of Susskind-Glogower theory. The phase-(particle) number uncertainty has a simple form in this formalism. |
