We report a very-large-scale silicon photonic quantum chip, on which we prepare various four-level four-qudit graph states and use them to demonstrate high-dimensional one-way quantum computation and measurement-based quantum algorithm.

We develop integrated spontaneous photon sources in silicon photonics simultaneously satisfying all requirements for large-scale photonic quantum computing: 0:9904 ± 0:0006 spectral purity, 0:985 ± 0:002 indistinguishability, > 90% heralding efficiency, and 0:96 ± 0:02 on-chip heralded quantum interference visibility.
