There is no measurement that can directly observe the wave function of a quantum mechanical system, but the wave function is still enormously useful as its (complex) square represents the probability ...

Physicists are increasingly using ultracold molecules to study quantum states of matter. Many researchers contend that molecules have advantages over other alternatives, such as trapped ions, atoms or ...

Researchers at the Department of Energy's Oak Ridge National Laboratory are helping to pave a path for the eventual discovery of dark matter. With new approaches to measurement in the quantum realm, ...
