Quantum mind with a cat in a locked steel chamber, wherein the cat's life or death depended on the state of a radioactive atom, whether it had decayed and emitted radiation or not. According to Schrödinger, the Copenhagen interpretation implies that "the cat remains both alive and dead" until the state has been observed. Schrödinger did not wish to promote the idea of dead-and-alive cats as a serious possibility; on the contrary, he intended the example to illustrate the absurdity of the existing view of quantum mechanics. However, since Schrödinger's time, other interpretations of the mathematics of quantum mechanics have been advanced
Quantum eraser experiment Quantum eraser experiment In quantum mechanics, the quantum eraser experiment is an interferometer experiment that demonstrates several fundamental aspects of quantum mechanics, including quantum entanglement and complementarity. The double-slit quantum eraser experiment described in this article has three stages: A key result is that it does not matter whether the eraser procedure is done before or after the photons arrive at the detection screen. Quantum erasure technology can be used to increase the resolution of advanced microscopes. The quantum eraser experiment described in this article is a variation of Thomas Young's classic double-slit experiment. It establishes that when action is
