Unpublished Schrödinger Manuscript Reveals His Challenge to Quantum Randomness Claims - The Quantum Insider

There is an old adage that we ‘make our own luck’. There is, in fact, plenty of scientific evidence to back this up. Experiments have shown that ‘lucky’ people are less anxious, more intuitive and more resilient than those who regard themselves as ‘unlucky’.

At some point between the tiny world of particles and atoms and the much larger world we experience every day, quantum behavior appears to fade away. Quantum mechanics allows particles to exist in combinations of possible states, a phenomenon known as superposition. That strange feature inspired Schrödinger's famous thought experiment involving a cat that is both alive and dead until it is observed. Yet objects in the everyday world do not behave that way.

Quantum phenomena are usually associated with extremely small objects such as individual atoms, molecules, or photons that must be carefully isolated from their surroundings. But can those same strange quantum effects also exist in objects large enough to see and hold? Researchers at TU Wien have now provided compelling evidence that they can. By studying a centimeter-sized crystal made from a type of material known as a strange metal, the team detected a high degree of quantum entanglement, one of the most remarkable features of quantum physics. They accomplished this using a technique from quantum information science called quantum Fisher information.
