Boson Sampling in a reconfigurable continuously-coupled 3D photonic circuit
Boson Sampling is a computational paradigm representing one of the most
viable and pursued approaches to demonstrate the regime of quantum advantage.
Recent results have demonstrated significant technological leaps in
single-photon generation and detection, leading to progressively larger
experimental instances of Boson Sampling experiments in different photonic
systems. However, a crucial requirement for a fully-fledged platform solving
this problem is the capability of implementing large scale interferometers,
that must simultaneously exhibit low losses, high degree of reconfigurability
and the realization of arbitrary transformations. In this work, we move a step
forward in this direction by demonstrating the adoption of a novel compact and
reconfigurable 3D-integrated platform for photonic Boson Sampling. We perform
3- and 4-photon experiments by using such platform, showing the possibility of
programming the circuit to implement a large number of unitary transformations.
These results show that such compact and highly-reconfigurable layout can be
scaled up to experiments with larger number of photon and modes, and can
provide a viable direction for hybrid computing with photonic processors.Comment: 17 pages, 14 figure
