Researchers have come up with a method that allows measuring the strength of the coherence of superposition in any given quantum state, similar to the famous Schrödinger's cat, which described as being simultaneously dead and alive. The method is based on the measurement of experimental parameters related to the visibility of the interference fringes pattern produced when the two states are superimposed.
