  Recent advances in quantum information and quantum science have inspired the
development of various compact dynamic structured ans\"{a}tze that are expected
to be realizable in the Noisy Intermediate-Scale Quantum (NISQ) devices.
However, such ans\"{a}tze construction strategies hitherto developed involve
considerable measurements, and thus they deviate significantly in NISQ platform
from their ideal structures. Therefore, it is imperative that the usage of
quantum resources must be minimized while retaining the expressivity and
dynamical structure of the ansatz that can adapt itself depending on the degree
of correlation. We propose a novel ansatz construction strategy based on the
\textit{ab-initio} many-body perturbation theory that requires \textit{no}
pre-circuit measurement and thus it remains structurally unaffected by any
hardware noise. The accuracy and quantum complexity associated with the ansatz
are solely dictated by a pre-defined perturbative order as desired and hence
are tunable. Furthermore, the underlying perturbative structure of the ansatz
construction pipeline enables us to decompose any high-rank excitation that
appears in higher perturbative orders into the product of various low-rank
operators, and it thus keeps the execution gate-depth to its minimum. With a
number of challenging applications on strongly correlated systems, we
demonstrate that our ansatz performs significantly better, both in terms of
accuracy, parameter count and circuit depth, in comparison to the allied
unitary coupled cluster based ans\"{a}tze.
