Fractional Hadamard transform with continuous variables in the context of quantum optics
Li-yun Hu, Xue-xiang Xu, Shan-jun Ma
We introduce the quantum fractional Hadamard transform with continuous variables. It is found that the corresponding quantum fractional Hadamard operator can be decomposed into a s…

New application of Dirac's representation: N-mode squeezing enhanced operator and squeezed state
Xue-xiang Xu, Li-yun Hu, Hong-yi Fan
It is known that exp[i\lamda(Q_1P_1-i/2)] is a unitary single-mode squeezing operator, where Q_1,P_1 are the coordinate and momentum operators, respectively. In this paper we emplo…
