  The BPS D3 brane has a non-supersymmetric cousin, called the non-susy D3
brane, which is also a solution of type IIB string theory. The corresponding
counterpart of black D3 brane is the `black' non-susy D3 brane and like the BPS
D3 brane, it also has a decoupling limit, where the decoupled geometry (in the
case we are interested, this is asymptotically AdS$_5$ $\times$ S$^5$) is the
holographic dual of a non-conformal, non-supersymmetric QFT in
$(3+1)$-dimensions. In this QFT we compute the entanglement entropy (EE), the
complexity and the Fisher information metric holographically using the above
mentioned geometry for spherical subsystems. The fidelity and the Fisher
information metric have been calculated from the regularized extremal volume of
the codimension one time slice of the bulk geometry using two different
proposals in the literature. Although for AdS black hole both the proposals
give identical results, the results differ for the non-supersymmetric
background.
