#### Superposition, Entanglement, and Raising Schrödinger’s Cat

In 1935, Erwin Schrödinger, one of the inventors of quantum mechanics, illustrated his discomfort with the theory by pointing out that its extension to the macroscopic world could lead to bizarre situations such as a cat being simultaneously alive a....

The founders of quantum theory assumed in 'thought experiments' that they were manipulating isolated quantum systems, obeying the counterintuitive laws which they had just discovered. Technological advances have recently turned these virtual experi....

The early days of the quantum theory presented many dilemmas connected with interference phenomena and what we have come to call the entanglement of states. We are much better able to deal with these problems now, both in theory and experiment, but t....

Cold, quantum degenerate gases of neutral atoms have proved to be useful in simulating the behavior of quantum systems like electrons in solids. For example, cold atoms moving in optical lattices (periodic potentials created by interfering laser be....
