  Our study employs a connected correlation matrix to quantify Quantum
Entanglement. The matrix encompasses all necessary measures for assessing the
degree of entanglement between particles. We begin with a three-qubit state and
involve obtaining a mixed state by performing partial tracing over one qubit.
Our goal is to exclude the non-connected sector by focusing on the connected
correlation. This suggests that the connected correlation is deemed crucial for
capturing relevant entanglement degrees. The study classifies mixed states and
observes that separable states exhibit the lowest correlation within each
class. We demonstrate that the entanglement measure monotonically increases
concerning the correlation measure. This implies that connected correlation
serves as an effective measure of Quantum Entanglement. Finally, our proposal
suggests that interpreting Quantum Entanglement from a local perspective is
possible. The observable is described as a vector with locality but violates
freedom of choice.
