The ability to control multidimensional quantum systems is central to the development of advanced quantum technologies.We demonstrate a multidimensional integrated quantum photonic platform able to generate, control, and analyze high-dimensional entanglement. A programmable bipartite entangled system is realized with dimensions up to 15 × 15 on a large-scale silicon photonics quantum circuit.The device integrates more than 550 photonic components on a single chip, including 16 identical photon-pair sources.We verify the high precision, generality, and controllability of ourmultidimensional technology, and further exploit these abilities to demonstrate previously unexplored quantum applications, such as quantum randomness expansion and self-testing on multidimensional states. Our work provides an experimental platform for the development of multidimensional quantum technologies.
