| 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 ). |
| Keywords: | generalized Hadamard transformation entangled state technique of integral within an ordered product |
