The quantum mechanics of photon addition and subtraction
... By adding only one photon, any input state is converted into a nonclassical state that cannot be described by classical theory. As seen in Figure 2, we added a photon to a thermal field (the most classical field) which makes the state have negative values in its Wigner function. This is a typical si ...

... as in classical mechanics. "Linearity" means that given two quite different states, each a solution of the equations of motion, the sum of the two states (with arbitrary coefficients) is also a solution. From a mathematical point of view, this is at the heart of the measurement problem; it is called ...
