New half-meter record for quantum superposition at macroscopic level

(Phys.org)—A team of researchers working at Stanford University has extended the record for quantum superposition at the macroscopic level, from 1 to 54 centimeters. In their paper published in the journal Nature, the team describes the experiment they conducted, their results and also discuss what their findings might mean for researchers looking to find the cutoff point between superposition as it applies to macroscopic objects versus those that only exist at the quantum level.
