A Quantum Tanimoto Coefficient Fidelity Measure for Entanglement Measurement

Authors: Yangyang Zhao, Fuyuan Xiao

Fidelity plays an important role in quantum information processing, which provides a basic scale for comparing two quantum states. At present, one of the most commonly used fidelity is Uhlmann-Jozsa (U-J) fidelity. However, U-J fidelity needs to calculate the square root of the matrix, which is not trivial in case of large or infinite density matrices. Moreover, it is found that U-J fidelity has limitations in some cases and can not well reflect the similarity between quantum states. Therefore, a novel quantum fidelity measure called quantum Tanimoto Coefficient (QTC) fidelity is proposed in this paper.
