The Efficiency of Quantum Identity Testing of Multiple States

Preprint English OPEN
Kada, Masaru; Nishimura, Harumichi; Yamakami, Tomoyuki;

We examine two quantum operations, the Permutation Test and the Circle Test, which test the identity of n quantum states. These operations naturally extend the well-studied Swap Test on two quantum states. We first show the optimality of the Permutation Test for any inp... View more
