摘要
引入了(A,B)-量子测量的概念,建立了(A,B)-量子测量与以A,B为下、上界的g-框架之间的等价关系,并得到它的直和与乘积运算的一些性质。引入了(A,B)-量子测量的对偶量子测量与测量框架算子,给出了典型对偶的构造方法,通过(A,B)-量子测量,得到了量子态的重构公式。
The concept of a(A,B)-quantum measurement is introduced and discussed.An equivalent relation between(A,B)-quantum measurement and g-frame with lower and upper bounds A and B is established.Some properties of direct sums and multiplications of(A,B)-quantum measurements are obtained.The measure frame operator and the dual quantum measurement of a(A,B)-quantum measurement are introduced and its canonical dual is constructed.Finally,a reconstruction formula of a quantum states is obtained in light of a(A,B)-quantum measurement.
