Query: Coherently controlled quantum features in a coupled interferometric
  scheme   Over the last several decades, entangled photon pairs generated by
spontaneous parametric down conversion processes in both second-order and
third-order nonlinear optical materials have been intensively studied for
various quantum features such as Bell inequality violation and anticorrelation.
In an interferometric scheme, anticorrelation results from photon bunching
based on randomness when entangled photon pairs coincidently impinge on a beam
splitter. Compared with post-measurement-based probabilistic confirmation, a
coherence version has been recently proposed using the wave nature of photons.
Here, the origin of quantum features in a coupled interferometric scheme is
investigated using pure coherence optics. In addition, a deterministic method
of entangled photon-pair generation is proposed for on-demand coherence control
of quantum processing.
