Physicists Achieve Record-Breaking Schrodinger's Cat Experiment.
Physicists at the Swiss Federal Institute of Technology in Zurich have created the largest-ever Schrodinger's Cat by putting a sapphire crystal weighing 16 micrograms in a quantum-mechanical superposition of two vibrational states. The crystal was excited into vibrations such that its atoms oscillated back and forth simultaneously and in two opposite directions, putting the entire crystal in a state of quantum superposition. The findings have pushed the envelope on what can be considered quantum mechanical in an actual lab experiment, demonstrating that something as massive as 16 micrograms can exist in this state.
