Scientists entangling quantum particles and even whole atoms has been in the news a lot over the past couple of years as experiments have been conducted with the goal of attempting to better understand the strange phenomenon—and much has been learned. But, as scientists figure out how to entangle two particles at ever greater distances apart there has come questions about the size of objects that can be entangled. Schrödinger’s cat has come up in several such discussions as theorists and those in the applied fields seek to figure out if it might be truly possible to cause a whole cat to actually be in two places at once...
