我们通过 SLOCC 不变量和半不变量的方式证明了四个量子位至少有 28 个不同的真随机局域运算和经典通信 (SLOCC) 纠缠类，并推导了 n 个量子位的简并 SLOCC 类的数量。
We show there are at least 28 distinct true stochastic local operations and classical communication (SLOCC) entanglement classes for four qubits by means of SLOCC invariant and semi-invariants and derive the number of degenerate SLOCC classes for n qubits.
