  Recently, an explicit relation between a measure of entanglement and a
geometric entity has been reported in Quantum Inf. Process. (2016)
15:1629-1638. It has been shown that if a qubit gets entangled with another
ancillary qubit then negativity, up to a constant factor, is equal to square
root of a specific Riemannian metric defined on the metric space corresponding
to the state space of the qubit. In this article, we consider the different
class of bi-partite entangled states and show explicit relation between two
measures of entanglement and Riemannian metric.
