Is the cat in the box alive, dead or... alive-dead? Questions like the one posed by the Schroedinger's Cat thought experiment have vexed mere mortals for far too long, and the scientific community knows that quantum mechanics is pretty tough to wrap our human brains around. So, a group of researchers at the University of Vienna developed an algorithm to help speed the quantum experimentation process along and make it altogether easier, according to APS Physics. It's dubbed Melvin and it was used in a quantum optics experiment to arrange mirrors and beam splitters to make quantum-entangled photons. Photons in Greenberger-Horne-Zeilinger states, specifically.
