有界不确定性关系提供了最小值的不确定性,假设一些额外的信息的状态。我们推导出解析的不确定性关系的一对约束,纯度和高斯性。在极限情况下,这种不确定性关系再现了由V I Man'ko和V V Dodonov导出的纯度有界和高斯性有界[Phys. Rev. A 86,030102R(2012)]。
英文摘要:
Bounded uncertainty relations provide the minimum value of the uncertainty assuming some additional information on the state. We derive analytically an uncertainty relation bounded by a pair of constraints, those of purity and Gaussianity. In a limiting case this uncertainty relation reproduces the purity-bounded derived by V I Man'ko and V V Dodonov and the Gaussianity-bounded one [Phys. Rev. A 86, 030102R (2012)].
