How this works (embed, share, limits)
  • Language: OpenQASM 2.0. Paste QASM 3 and we'll translate common constructs (qubit[N], bit[N], include "stdgates.inc") automatically.
  • Simulation: pure-JavaScript state-vector simulator ( quantum-circuit ) running on your own CPU. 12 qubits is comfortable; 16 starts to lag.
  • Share: the Share button base64-encodes the QASM into the URL. Anyone opening the link sees the same circuit with the same state.
  • Embed: add ?embed=1 to the URL for a frame-friendly layout without the site chrome.
  • Privacy: your circuit never leaves the browser.
