A paper or a design review usually wants one table: circuit size against depth and gate count, for a few register sizes and error targets. oqft stats prints all of it, …

OQFT asks for one number besides the register size: the error target, --eps. It’s the average squared error you’re willing to accept over all inputs. Pick it …

The block width is the one knob inside an optimistic QFT. Narrow blocks make a shallow circuit that fails often. Wide blocks fail rarely but cost more depth. OQFT …
testing
A circuit generator can produce something that looks fine, loads fine, and computes the wrong thing. The only way to know is to run the circuit and compare. OQFT does …

Ask a circuit designer for a quantum Fourier transform and they’ll want it right on every input. That’s the normal bar. A circuit is a fixed piece of …

The quantum Fourier transform sits in the middle of Shor’s algorithm. Build it the textbook way on 2,048 qubits, the size you’d need for a 2048-bit RSA key, …

The optimistic QFT is built for big registers. Everyone working with it knows that. The less obvious question is where “big” starts, because below some size …

OQFT is four letters and one idea. The last three, QFT, are the quantum Fourier transform, one of the most used building blocks in quantum computing. The O is the new …
