Imaginarity measures induced by relative entropy (2404.00637v2)

Published 31 Mar 2024 in quant-ph

Abstract: In this paper, we introduce two measures for the resource theory of imaginarity. One is induced by $\alpha$--$z$--R\'enyi relative entropy and the other, defined for positive definite density matrices, is induced by Tsallis relative operator entropy. The relationships between different imaginarity measures and their properties are also discussed.
