With a unitary quantum cloner, because it generates micro-macro entanglement, if we amplify one of the entangled photons using the cloner, does that mean that the corresponding macroscopic amplification is in a superposition (a superposition of V and H polarisation) until measurement? Would we see a violation of the CHSH inequality?(adsbygoogle = window.adsbygoogle || []).push({});

Also, if we measure the polarisation of the other photon, then send the partner photon into the unitary quantum cloner, would that produce the same result as a measure & prepare cloner (hence not produce a micro-macro entangled state), and thereby expect no violation of the CHSH inequality?
