Query: Hybrid entanglement between optical discrete polarizations and
  continuous quadrature variables   By coherently combining advantages while largely avoiding limitations of two
mainstream platforms, optical hybrid entanglement involving both discrete and
continuous variables has recently garnered widespread attention and emerged as
a promising idea for building heterogenous quantum networks. Different from
previous results, here we propose a new scheme to remotely generate hybrid
entanglement between discrete-polarization and continuous-quadrature optical
qubits heralded by two-photon Bell state measurement. As a novel nonclassical
light resource, we further utilize it to discuss two examples of ways --
entanglement swapping and quantum teloportation -- in which quantum information
processing and communications could make use of this hybrid technique.
