Could you build this?
No Simulating a 1000-qubit quantum circuit on standard consumer hardware without a GPU requires cutting-edge tensor network contraction algorithms, stabilizer rank decompositions, or novel mathematical shortcuts far beyond vibe coding.
What it would actually take: Simulating 1,000 arbitrary qubits requires representing a $2^{1000}$ state vector, which is physically impossible; doing so for specific circuits requires sophisticated tensor network simulators (MPS/PEPS) or Clifford+T approximations implemented in C++ or Rust with extreme memory efficiency. Developing such a simulator demands deep academic expertise in quantum computing, linear algebra, and specialized numerical optimization algorithms.
Discussion
4 comments analyzed.
Competitors mentioned: BlueQubit CPU/GPU simulators, Other exact statevector simulators
Concerns raised: Limited to structured/low-entanglement circuits, not general-purpose 1000-qubit simulation, Strictly worse performance for highly entangled circuits, Hard ceiling on qubit count despite MPS approach
