QBridge

State-vector simulator. The C++, Python and JavaScript engines in this repository run the same .qc circuits; this page runs the JavaScript one and checks it against the Python reference.

Same syntax as the .qc files: qubits N, then one gate per line (h, x, y, z, s, t, p, rx, ry, rz, cx, cz, cp, ccx, swap). Angles accept pi/2 style tokens.
