Efficient Implementation of Controlled-Rotations by Using Entanglement
Ming-Yong Ye, Yong-Sheng Zhang, Guang-Can Guo
Abstract
Implementation of controlled-rotations using entanglement is considered. We show that the successful probability is closely related to the entanglement and the rotation angle. The successful probability will increase if we increase the entanglement we use or decrease the controlled-rotation angle and the probability will trend to unit when the entangled state trends to a Bell state or the controlled-rotation angle trends to zero.
