Paul Dirac described the superposition principle as follows:
The general principle of superposition of quantum mechanics applies to the states [that are theoretically … See more

General formalism
Any state can be expanded as a sum of the eigenstates of an Hermitian operator, like the Hamiltonian, because the eigenstates form a … See more

Uniform quantum superposition states describe quantum systems that exist in a linear combination of multiple basis states, with each basis … See more

It is natural to ask why ordinary everyday objects and events do not seem to display quantum mechanical features such as superposition. Indeed, this is sometimes regarded as … See more

Successful experiments involving superpositions of relatively large (by the standards of quantum physics) objects have been performed. See more

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 … See more
