Query: Quadrature protection of squeezed states in a one-dimensional photonic
  topological insulator   What is the role of topology in the propagation of quantum light in photonic
lattices? We address this question by studying the propagation of squeezed
states in a topological one-dimensional waveguide array, benchmarking our
results with those for a topologically trivial localized state, and studying
their robustness against disorder. Specifically, we study photon statistics,
one-mode and two-mode squeezing, and entanglement generation when the localized
state is excited with squeezed light. These quantum properties inherit the
shape of the localized state but, more interestingly, and unlike in the
topologically trivial case, we find that propagation of squeezed light in a
topologically protected state robustly preserves the phase of the squeezed
quadrature as the system evolves. We show how this latter topological advantage
can be harnessed for quantum information protocols.
