<正> There exists rare integration formulas over quaternions due to the noncommutativity of quarternions mult-plication.Based on the class operator's formul
<正> Our primary purpose of this work is to explicitly construct the general multipartite Einstein Podolsky-Rosen (EPR) entangled state in muIti-mode Fock space
<正> Based on our previous paper (Commun.Theor.Phys.39 (2003) 417) we derive the convolution theoremof fractional Fourier transformation in the context of quant
<正> We propose a scheme for approximately and conditionally teleporting an unknown atomic-entangled statein dissipative cavity QED.It is the further developmen
