利用纠缠有效实现受控旋转

Efficient Implementation of Controlled-Rotations by Using Entanglement

Ming-Yong Ye, Yong-Sheng Zhang, Guang-Can Guo

摘要:

利用纠缠实现受控旋转。结果表明,成功的几率与纠缠度和旋转角度密切相关。随着纠缠度的增大或控制旋转角的减小,成功几率增大,当纠缠态趋于Bell态或控制旋转角趋于零时,成功几率趋于单位。

英文摘要:

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.
