基于Gisin在2019年提出的联合测量ElegantJointMeasurement(EJM),本文对量子隐形传态过程进行初步探讨。计算EJM测量后量子态的演化过程,重点研究θ=0和θ=π/2两种情况下系统恢复待传送未知量子态的演化矩阵。结果表明,θ=π/2时的演化矩阵是幺正矩阵,而θ=0时的演化矩阵是非幺正矩阵。

We discuss the quantum teleportation based on the Elegant Joint Measurement (EJM) proposed byGisin in 2019.We research the evolution of quantum state after EJM measurement and typically calculate theevolution matrices to recover the unknown quantum state for θ= 0 and θ=π/ 2.As a result, the evolution matrices are non-unitary matrices for θ= 0, and they are unitary for θ=π/ 2.
