Abstract
We invoke the black-hole-qubit correspondence to derive the classification of four-qubit entanglement. The U-duality orbits resulting from timelike reduction of string theory from D=4 to D=3 yield 31 entanglement families, which reduce to nine up to permutation of the four qubits.
摘要
我们援引黑洞-量子比特对应关系来推导出四量子比特纠缠的分类。从 D=4 降至 D=3 的弦论的类时约化产生的 U 对偶轨道产生了 31 个纠缠族，这在四量子比特的排列下减少到了 9 个。
