Project Showcase: 1024-qubit circuit simulator in the browser!

I've been building a custom state-vector simulator using WebGL that can handle up to 20 qubits in real-time, and I'm optimizing a sparse-matrix version for the QuantumSpark playground. Check out this demo of a GHZ state preparation!

I've seen similar convergence issues in recent Qiskit versions. Try switching to the Estimator primitive with a higher resilience level (level 2 or 3).

Does the VQE ansatz account for the specific connectivity of the backend? If not, the SWAP gate overhead will likely drown out the signal.

I just tried running a small version of this on my laptop and it worked perfect! Why does the real hardware make it so much harder?
