#3Cool! I am curious, how does it work and compare to other simulators like the ones from Bluequbit (https://www.bluequbit.io/free-quantum-simulator) and other similar ones?

#4If I'm understanding this correctly, it doesn't simulate any general purpose quantum circuit with 1000 qubits, only ones where there's a more efficient strategy than an exponential state where exact simulation is feasible.

> We support 34-qubit CPU and 36-qubit GPU simulators available 24/7 to our users.
This one looks like an exact simulator that handles exponential states, so it's far more limited in the number of qubits it can support.

BlueQubit's CPU/GPU simulators are exact statevectors — they store the full 2^n amplitude vector, so 34–36 qubits is the hard ceiling regardless of circuit structure. We take a different approach: MPS/tensor-network representation that scales with entanglement rather than qubit count. For highly entangled circuits we're strictly worse. For structured circuits (most variational, most shallow) we can go much larger. Complementary tools really.
