Schrödinger’s Second Cat is a Thing. Not Just a Big Bang Theory
Yale (University) News reports that the school’s “physicists have given Schrödinger’s famous cat a second box to play in, and the result may help further the quest for reliable quantum computing.”
In the new experiment, the “cat lives or dies in two boxes at once, which is a marriage of the idea of Schrödinger’s cat and another central concept of quantum physics: entanglement. Entanglement allows a local observation to change the state of a distant object instantaneously.”
The paradoxical Schrödinger’s Cat thought experiment is explained in this stick figure video: Schrödinger’s Cat.
For a another take, here’s Sheldon explaining the theory to Penny in The Big Bang Theory – Schrodinger’s cat.
