Physicists have created the world's heaviest Schrödinger's cat, bringing the bizarre behavior of the quantum world to larger scales than ever before.
Taking its name from Erwin Schrödinger's famous thought experiment, the new Schrödinger's cat crystal could be used to design more robust quantum computers and reveal clues behind why quantum effects are not seen in the real world, according to the researchers. Their findings were published April 20 in the journal Science .
To achieve this, the physicists connected the vibrating part of the sapphire crystal to a superconducting circuit, shaking it in such a way that it began to vibrate in a superposition of two directions at once.
