Comment on efficient and feasible quantum private comparison of equality against the collective amplitude damping noise
TL;DR: In this improved scheme, only the two players can deduce the results of comparisons based on their shared key, and others will learn no information of the comparison results, even the length of secrets, and the cost of communication is also be optimized.
