论文摘要
众所周知，基于弱测量结果的协议可用于将量子系统转向预先指定的纯状态。在这里，我们表明，可以利用基于弱测量的转向协议，用于$ \ textit {混合} $状态的按需工程。特别是，通过协议参数的持续变化，可以将经典目标状态引导到不一致的目标状态，然后再向前朝纠缠的目标状态。
It is known that protocols based on weak measurements can be used to steer quantum systems into pre-designated pure states. Here we show that weak-measurement-based steering protocols can be harnessed for on-demand engineering of $\textit{mixed}$ states. In particular, through a continuous variation of the protocol parameters, one can guide a classical target state to a discorded one, and further on, towards an entangled target state.
