Classical bits can be in one of two states 0 or 1, but a qubit can be in a superposition of those. Thus the number of states increase exponentially so does the computational power.
I understand that the number of avalable states obviously plays a major role in the computational power but I don't understand what is the effect of the continuous range of the values of a qubit on that computational power.
Contrary to the classical bit, a qubit can have an infinite number of values, those on the surface of the Bloch sphere (at least until it is measured), so:
- How do the availability of infinite values affect the computational power? In a classical computer a bit is bound to use 0 and 1 but when a qubit can have an infinite amount of values how is the performance affected?
- What aspects of the quantum computer are affected by the availability of those infinite values?
