Could you build this?
No Writing a quantum circuit simulator from scratch in C++ requires rigorous quantum mechanics knowledge, complex matrix math, and high-performance numerical optimization.
What it would actually take: Requires implementing state-vector and density-matrix quantum mechanics representations, tensor operations, gate decomposition, and unitary matrix transformations in C++. The system needs high-performance computing libraries (BLAS/LAPACK, OpenMP, or SIMD) and specialized physics expertise in quantum computing theory.
