In a real-life use of Schrödinger's theoretical paradoxical cat, researchers report that they were able to quickly transfer a complex set of quantum information while preserving its integrity. The information, in the form of light, was manipulated in such a way that it existed in two states at the same time, and it was destroyed in one spot and recreated in another. The new breakthrough is a major step toward building safe, effective quantum computers.
No felines were harmed in the making of this experiment, which actually studied wave packets of light that existed in a state of quantum superposition, meaning they existed in two different phases simultaneously. This phenomenon is described in Erwin Schrodinger’s quantum mechanics thought experiment, in which a cat is simultaneously dead and alive, depending on the state of a subatomic particle.
In this experiment, researchers in Australia and Japan were able to....
