Last year, we proposed a way of realizing frequency-domain linear quantum circuit using spectrally shaped ultrafast single photons, and demonstrated Hong-Ou-Mandel interference. Now we will report the improvement of visibility, and scheme for large-scale linear optics using frequency-time transformation by Chirped fiber Bragg grating and demonstrate it.
