The "entropy bit mixing" method. This method mixes (XORs) parameter values represented as raw bit strings drawn from an odd number of parameter vectors. Probabilistically, such composition creates a new random parameter vector, with an overwhelming number of bits being common to the better-performi...
In analogy to entropy of observable states in the classical dynamic systems, a phase shift, which can be expressed by the unitary quantum derivative operator, leads to a change of qubit states through the phase loops on the surface of the Bloch sphere, and this effect results in the increase...
