Abstract: We report the realization of the largest reconfigurable quantum photonic processor enabling arbitrary unitary transformations on its 20 input & output modes with an average fibre-to-fibre loss of 2.9 dB/channel. High-fidelity operation and high-visibility quantum interference is demonstrated.
