We investigate the local quantum uncertainty (LQU ) in weak measurement. An expression of weak LQU is explicitly determined. Also, we consider some cases of three special X states, Werner state, circulant two-qubit states, and Heisenberg model via LQU in normal and weak measurements. We find that the LQU in weak measurement is weaker than the case of strong measurement.

弱测量对量子相关性的影响

我们研究了弱测量中的局部量子不确定性（LQU）。弱 LQU 的表达式是明确确定的。此外，我们在正常和弱测量中通过 LQU 考虑了三种特殊X状态、Werner 状态、循环双量子比特状态和 Heisenberg 模型的一些情况。我们发现弱测量的 LQU 比强测量的情况要弱。
