We present a holographic set up that computes timelike Entanglement Entropy (tEE) in (0 + 1)d QFTs preserving some amount of SUSY. The first example we consider is that of \( \mathcal{N} \) = 2 matrix models with massive deformations. These are dual to non-Abelian T-dual of AdS5 × S5 that asymptotes to smeared D0 branes. The second example, that we consider is of \( \mathcal{N} \) = 4 superconformal quantum mechanical quivers in (0 + 1)d that are dual to a class of type IIB backgrounds with an AdS2 factor. In both of these examples, tEE reveals a remarkable similarity with holographic c function pertaining to a RG flow. We further compute the complexity in these models, which also reveals an identical behaviour indicating the fact that tEE is a measure of number of degrees of freedom for these (0 + 1)d SQFTs in a RG flow from UV to deep IR.
