Query: Do Quantum Nonlocal Correlations Imply Information Transfer?- A Simply
  Quantum Optical Test   In order to understand whether nonlocality implies information transfer, a
quantum optical experimental test, well within the scope of current technology,
is proposed. It is essentially a delayed choice experiment as applied to
entangled particles. The basic idea is: given two observers sharing
position-momentum entangled photons, one party chooses whether she measures
position or momentum of her photons after the particles leave the source. The
other party should infer her action by checking for the absence or presence of
characteristic interference patterns after subjecting his particles to certain
optical pre-processing. An occurance of signal transmission is attributed to
the breakdown of complementarity in incomplete measurements. Since the result
implies that the transferred information is classical, we discuss some
propositions for safeguarding causality.
