Quantum 10, 2093 (2026). https://doi.org/10.22331/q-2026-05-05-2093 Quantum circuit simulation is paramount to the verification and optimization of quantum algorithms, and considerable research efforts have been made towards efficient simulators. While circuits often contain high-level gates such as oracles and multi-controlled $X$ ($C^kX$) gates, existing simulation methods require compilation to a low-level gate-set before simulation. This, however, increases circuit size and incurs a consider
