"...entanglement between objects....visible to humans."
Based on everything that we've been fed for decades regarding that 'Observation Effect' thingy, I presume not 'entangled' and 'visible' at the same time.
In other words, 'The Cat Must Be In A Box.'
I wonder if we'll finally be permitted to peek, given that just a few wafer-thin photons shouldn't bother a macroscopic clump all that much.
