Query: 8x8 Reconfigurable quantum photonic processor based on silicon nitride
  waveguides   The development of large-scale optical quantum information processing
circuits ground on the stability and reconfigurability enabled by integrated
photonics. We demonstrate a reconfigurable 8x8 integrated linear optical
network based on silicon nitride waveguides for quantum information processing.
Our processor implements a novel optical architecture enabling any arbitrary
linear transformation and constitutes the largest programmable circuit reported
so far on this platform. We validate a variety of photonic quantum information
processing primitives, in the form of Hong-Ou-Mandel interference, bosonic
coalescence/anticoalescence and high-dimensional single-photon quantum gates.
We achieve fidelities that clearly demonstrate the promising future for
large-scale photonic quantum information processing using low-loss silicon
nitride.
