QP101-ZY circuit diagrams

From Stim circuit to SVG or JSON

QP101 is a JSON format for circuit diagrams. It preserves gates, repeat blocks, detectors, noise and coordinates in execution order.

Create circuit.stim in your working directory.

circuit.svg shows the two-qubit circuit; circuit.qp101.json is its ordered circuit document.

R resets a qubit; XE marks a possible X error, and the filled dot is the CNOT control. M marks a measurement. D0 and D1 label detector checks; L0 labels the logical parity. This is the circuit definition, before sampling a shot.
