Integrated photonics is an essential technology for quantum computing. Universal, phase-stable, reconfigurable quantum photonic processors enable manipulation of quantum states of light and are one of the main components of photonic quantum computers. In this work [1], we report the realization of the largest quantum photonic processor to date. The processor is realized in Si3N4 waveguides, and it enables arbitrary unitary transformations on its 20 input modes with a fidelities above 97%, an average optical loss of 2.9dB per mode, and high-visibility quantum interference VHOM = 98%.
