sentences:  This relationship between stochastic systems and quantum systems sheds much light on supersymmetry.Successful experiments involving superpositions of relatively large (by the standards of quantum physics) objects have been performed.In quantum computing the phrase "cat state" often refers to the GHZ state, the special entanglement of qubits wherein the qubits are in an equal superposition of all being 0 and all being 1; i.e.,
  
  Applying the superposition principle to a quantum mechanical particle, the configurations of the particle are all positions, so the superpositions make a complex wave in space.
