    "abstract": "Quantum Fourier transform (QFT) is a key function to realize quantum\ncomputers. A QFT followed by measurement was demonstrated on a simple circuit\nbased on fiber-optics. The QFT was shown to be robust against imperfections in\nthe rotation gate. Error probability was estimated to be 0.01 per qubit, which\ncorresponded to error-free operation on 100 qubits. The error probability can\nbe further reduced by taking the majority of the accumulated results. The\nreduction of error probability resulted in a successful QFT demonstration on\n1024 qubits.",
