摘要:
复射影空间 $\mathbb{P}(\mathbb{C}^n)$ 可解释为所有规模为 $n$ 的量子纯态空间。从量子物理角度看,该空间上一个有趣的距离可由 $n$ 点概率单纯形上通过“推土机问题”定义的经典距离诱导而来。我们证明这一构造给出的量满足三角不等式,从而在复射影空间上产生一个真正的距离,且属于量子 $2$-Wasserstein 距离族。
英文摘要:
The complex projective space $\mathbb{P}(\mathbb{C}^n)$ can be interpreted as the space of all quantum pure states of size $n$. A distance on this space, interesting from the perspective of quantum physics, can be induced from a classical distance defined on the $n$-point probability simplex by the `earth mover problem'. We show that this construction leads to a quantity satisfying the triangle inequality, which yields a true distance on complex projective space belonging to the family of quantum $2$-Wasserstein distances.
