1. Remarks on the Sequential Products

Author

Weihua, Liu, Zhaoqi, Wu, and Junde, Wu

Subjects
Mathematical Physics
Abstract

In this paper, we show that those sequential products which were proposed by Liu and Shen and Wu in [J. Phys. A: Math. Theor. {\bf 42}, 185206 (2009), J. Phys. A: Math. Theor. {\bf 42}, 345203 (2009)] are just unitary equivalent to the sequential product $A\circ B=A^{\frac{1}{2}}BA^{\frac{1}{2}}$.

2. Non-disturbance criteria of quantum measurements

Author

Zhaoqi, Wu, Shifang, Zhang, and Junde, Wu

Subjects
Quantum Physics
Abstract

Using the general sequential product proposed by Shen and Wu in [J. Phys. A: Math. Theor. 42, 345203, 2009], we derive three criteria for describing non-disturbance between quantum measurements that may be unsharp with such new sequential products, which generalizes Gudder's results.
