  In recent years, quantum computing has evolved as an exciting frontier, with
the development of numerous algorithms dedicated to constructing quantum
circuits that adeptly represent quantum many-body states. However, this domain
remains in its early stages and requires further refinement to understand
better the effective construction of highly-entangled quantum states within
quantum circuits. Here, we demonstrate that quantum many-body states can be
universally represented using a quantum circuit comprising multi-qubit gates.
Furthermore, we evaluate the efficiency of a quantum circuit constructed with
two-qubit gates in quench dynamics for the transverse-field Ising model. In
this specific model, despite the initial state being classical without
entanglement, it undergoes long-time evolution, eventually leading to a
highly-entangled quantum state. Our results reveal that a diamond-shaped
quantum circuit, designed to approximate the multi-qubit gate-based quantum
circuit, remarkably excels in accurately representing the long-time dynamics of
the system. Moreover, the diamond-shaped circuit follows the volume law
behavior in entanglement entropy, offering a significant advantage over
alternative quantum circuit constructions employing two-qubit gates.
