Browser-native, research-grade quantum circuit editor, simulator & visualizer — statevector, Clifford-tableau & noisy-trajectory backends; 64 gates, ~65 analysis panels (40 visualizers), a benchmarking suite (RB/QV/XEB/QEC), nine SDK exports, and an AI assistant. No install, no account.

A dependency-free C quantum compiler. OpenQASM 3 in, verified IBM-native output, real superconducting hardware. The README screenshot is the actual DOOM title screen rendered via quantum measurement on ibm_marrakesh.
