摘要本文研究了基于非经典指针态的广义模值方案。我们考虑一个典型的冯诺依曼测量与离散量子指针,其中指针是一个投影到指针希尔伯特空间的基础的状态之一的操作。我们分别计算了相干态、相干压缩态和薛定谔猫指针态的条件概率、Qm因子和正交算符的信噪比,发现在以模值为特征的广义测量问题中,与半经典态相比,非经典猫指针态可以提高场的负性和测量精度。
AbstractIn this study, we investigate the generalized modular value scheme based on non-classical pointer states. We consider a typical von Neumann measurement with a discrete quantum pointer, where the pointer is a projection operator onto one of the states of the basis of the pointer Hilbert space. We separately calculate the conditional probabilities,Qmfactors, and signal-to-noise ratios of quadrature operators of coherent, coherent squeezed, and Schrödinger cat pointer states and find that the non-classical pointer states can increase the negativity of the field and precision of measurement compared with semi-classical states in generalized measurement problems characterized by the modular value.Graphical abstract
