  The significant global spin alignment observed for $\phi$ mesons in heavy-ion
collisions has sparked intense discussions about its origin and implications.
One explanation suggests that fluctuations in the strong force field may
introduce strong spin correlations between strange ($s$) and anti-strange
($\bar{s}$) quarks, leading to the global spin alignment of $\phi$ mesons.
Extending this line of research, the theoretical community has proposed
studying the spin correlation between $\Lambda$ and $\bar{\Lambda}$ hyperons.
In this paper, we construct experimental observables and make connections
between them and the theoretical proposed quantities.
