Hi,
I'm having trouble understanding the power of qubits relating to quantum computers. I've read a number of times that the power comes from the fact that instead of simply holding an on or off state (1/0), they can hold both at the same time (superposition). However, when we measure them they 'decide' on a state.
My question is, how can this third state of superposition provide a huge benefit over the 1 and 0 states of transistors, since once we use them (observe them) the states available to us is still only a 1 or a 0?
Many thanks in advance http://www.thephysicsforum.com/images/smilies/smile.png
