Quantum Operations: Arbitrary Initialization & State Fidelity

What if we want to initialize a qubit register to an arbitrary state?
An arbitrary state for n qubits may be specified by a vector of 2n (2 power n) amplitudes.

Fidelity is useful to check whether two states are the same or not.
The fidelity is equal to 1 if and only if two states are equal.
