摘要/Abstract

摘要： A new entangled state | eta ;theta rangle is proposed by the technique of integral within an ordered product. A generalized Hadamard transformation is derived by virtue of | eta ;theta rangle , which plays a role of Hadamard transformation for (hat a_1 sin theta - hat a_2 cos theta ) and (hat a_1 cos theta + hat a_2 sin theta ).

Abstract: A new entangled state $| {\eta ;\theta } \rangle $ is proposed by the technique of integral within an ordered product. A generalized Hadamard transformation is derived by virtue of $| {\eta ;\theta } \rangle $, which plays a role of Hadamard transformation for $(\hat {a}_1 \sin \theta - \hat {a}_2 \cos \theta )$ and $(\hat {a}_1 \cos \theta + \hat {a}_2 \sin \theta )$.

Key words: generalized Hadamard transformation, entangled state, technique of integral within an ordered product
