... • If we do it classically we have to calculate f(x) many times. – It isn’t how easy it is to calculate f(x), it is how many times. – Need to go from 0 to N2 , this is a huge number of calculations for a 128 bit number! This could be 2(2*128) or ~1.16 x 1077 – The results have to be stored somewhere ...

Implementations of Quantum Information
... The Hamiltonian generates unitary evolution, which corresponds to dynamics in a closed system, but the system must be open for preparation and readout. The openness is the coupling of the system to the environment; e.g. a puck sliding on ice is slowed by frictional coupling to ice and air resist ...

Fractal geometry enables information transmission through resonance
... extremely sensitive to even small changes, because of the nonlinear interactions that result from feedback operations and high global coherency within the system. As such, there is an indeterminate nature to fractal / chaotic systems, much like trying to predict the weather. So that in contrast to t ...

... the action allows us to describe the dynamics of a classical particle in a different manner in which the above example becomes very easy. 1.2. States, Observables, Measurement, and Dynamics. We begin with a question: given a path x(t) in Rn , how much information do we need to specify the motion of ...
