Photonic quantum computation plays an important role and offers unique advantages. Two decades after the milestone work of Knill-Laflamme-Milburn
various architectures of photonic processors have been proposed
and quantum advantage over classical computers has also been demonstrated. It is now the opportune time to apply this technology to real-world applications. However
at current technology level
this aim is restricted by either programmability in bulk optics or loss in integrated optics for the existing architectures of processors
for which the resource cost is also a problem. Here we present a von-Neumann-like architecture based on temporal-mode encoding and looped structure on table
which is capable of multimode-universal programmability
resource-efficiency
phase-stability and software-scalability. In order to illustrate these merits
we execute two different programs with varying resource requirements on the same processor
to investigate quantum signature of chaos from two aspects: the signature behaviors exhibited in phase space (13 modes)
and the Fermi golden rule which has not been experimentally studied in quantitative way before (26 modes). The maximal program contains an optical interferometer network with 1694 freely-adjustable phases. Considering current state-of-the-art
our architecture stands as the most promising candidate for real-world applications.
