稳定态的局域么正等价与局域Clifford等价

Local unitary versus local Clifford equivalence of stabilizer states

M. Van den Nest, J. Dehaene, B. De Moor

摘要:

研究了稳定态的局域么正等价与局域Clifford等价之间的关系。我们引入了一个大的子类的稳定状态,这样,每两个LU等价的状态在这个类中必然是LC等价的。与以前的结果一起,这表明LC,LU和SLOCC等价是这类稳定状态相同的概念。此外,识别当前子类中的两个给定稳定器状态是否局部等价仅需要量子比特数量的多项式数量的操作。

英文摘要:

We study the relation between local unitary (LU) equivalence and local Clifford (LC) equivalence of stabilizer states. We introduce a large subclass of stabilizer states, such that every two LU equivalent states in this class are necessarily LC equivalent. Together with earlier results, this shows that LC, LU and SLOCC equivalence are the same notions for this class of stabilizer states. Moreover, recognizing whether two given stabilizer states in the present subclass are locally equivalent only requires a polynomial number of operations in the number of qubits.
