摘要
我们扩展了苏达等人(Phys Rev A 102:052419, 2020)的数学框架,构建了纯三量子比特态的洛伦兹不变量。这种方法是众所周知的任意三量子比特纯态的局部单元(LU)不变量与其还原的二量子比特系统的洛伦兹不变量之间的桥梁。
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.
