Circuit

A circuit is a list of gates in order on named qubits, ending in measurements. OpenQASM 3, OpenQASM 2 and QPY are the files ROX OS reads; on upload you see qubits, depth and the number of two-qubit gates before anything runs.

The machine does not run your circuit as written. A transpiler maps it to the chip's native gates and connectivity. The vendor's default does this one way; ROX OS does it another — same circuit, chosen loop, protected schedule — and both are run side by side so the difference is measured, not claimed.

Folding: to measure how a circuit degrades with load, ROX OS runs U, then U·U†·U, then deeper. The ideal state is identical on every rung; only the noise dose grows. That is the folding ladder on the record.
