  Within the confining color flux tube picture, we assess the color electric
field generated by quark-antiquark pairs within the framework of the Schwinger
model and estimate its impact on the chiral condensate. We observe differences
in the distribution of the color flux tube generated by quark-antiquark pairs
at different separation distances, leading to discrepancies in the partial
restoration of chiral symmetry. Furthermore, we suggest incorporating the color
magnetic field in the calculation of chiral condensate, leading to quantum
entanglement effects, and proceed to compute the entanglement entropy. We
observe that the entanglement entropy increases with the distance of the color
source (the separation distance between quark and anti-quark), and the
magnitude of the color electric field and chiral condensate restoration after
spatial integration also increases with the distance of the color source. Then,
we try to provide a qualitative explanation for the existence of these
phenomena.
