摘要：
Extending the mathematical framework of Sudha et al. (Phys Rev A 102:052419, 2020), we construct Lorentz invariant quantities of pure three-qubit states. This method serves as a bridge between the well-known local unitary (LU) invariants of an arbitrary three-qubit pure state and the Lorentz invariants of its reduced two-qubit systems.
