John Clauser was one of the first physicists to investigate the strange and seemingly bizarre behavior of quantum mechanics. In particular, he discovered that quantum mechanics allows for what is known as “entanglement” between particles. This phenomenon is often described as “spooky action at a distance” and it violate classical ideas about causality and local realism. Clauser’s work on quantum mechanics helped to pave the way for the development of quantum information and quantum computing.

### Q: Who discovered the quantum mechanics theory?

A: Quantum mechanics was developed in the early 1900s by a number of physicists, including Max Planck, Niels Bohr, and Albert Einstein.

### Q: Who contributed the most to quantum mechanics?

A: There are many individuals who have made important contributions to quantum mechanics, including Max Planck, Albert Einstein, Niels Bohr, Werner Heisenberg, and Erwin SchrÃ¶dinger. It is difficult to say who has made the most important contributions, as each individual has made unique and important contributions to the field.

### Q: What did Richard Feynman say about quantum physics?

A: “Quantum mechanics is a very strange theory,” Feynman once said. “It’s so strange that I can’t really understand it myself.”
