  bibo_abstract:
  - <jats:p>For the ever-growing field of quantum information processing, large-scale,
    efficient multiport interferometers serving as photonic processors are required.
    In this context, the suitability of quantum walks as the interferometric base
    for universal computation has been theoretically proven. In this work, we bridge
    the gap between theoretical proposals and state-of-the-art experimental capabilities
    by providing the recipe for the implementation of a universal photonic processor
    in discrete-time quantum walks. Specifically, we present the protocol for translating
    arbitrary linear transformations into the coin and step operator of a quantum
    walk and map these to the experimental parameters of the established time-multiplexed
    platform [A. Schreiber , Phys. Rev. Lett. , 050502 (2010)]. We show that our interface
    is highly scalable and resource efficient due to the hybrid encoding consisting
    of multiple degrees of freedom. Finally, we prove that our system is highly resilient
    against experimental imperfections and show that it compares favorably against
    existing architectures.</jats:p>@eng
