Quantum Entanglement "Detected" By Human Eye

I'm not sure what to make of this.

My understanding, after reading the paper, is that they showed their experiment does NOT show micro-macro entanglement. It did show micro-micro entanglement of the original two photons before one was amplified. However, the amplification was, quantum mechanically, a measurement, so while it retained information about the original entanglement, it destroyed the entanglement itself between the single photon and the amplified stream of photons.

The open question is if you can amplify a photon retaining all the information of the wave function. If you can, you can see micro-macro entanglement. Otherwise, by amplifying it, you measure it and collapse the wave function.
