For readers who are new to the topic of Quantum Mechanics, you must watch the following youtube animation of the infamous double-slit-experiment just to get an idea of what this indeterminate revolutionary theory is. World renowned theoretical physicist late Physics Nobel Laureate Prof. Richard Feynman of CalTech (who himself was very impressed with Wolfram founder, scientist Dr. Stephen Wolfram when the young Wolfram was at CalTech) once quoted that if anyone can come up with a physical theory that explains the controversy of the double-split-experiment in a local manner (because quantum superposition is non-local, ie, material things can be here & there in different points of space at once which lead to the possibility that Falafulu Fisi is writing this post from his home in New Zealand and from California at the same time - I am at 2 places simultaneously), then that theory should supersede or make Quantum Mechanic obsolete.
Dr. Quantum - Double Slit Experiment (animation)
What is observed in the double-slit-experiment is fact (ie, undeniable), what is still debatable whether indeed the particle (electron) does indeed go thru the 2 slit holes at once. Quantum Mechanic (QM) says yes, where majority of Physicists agree with that interpretation, however there has never been any direct observation (ie, measured) and evidence that the particle (electron) does go thru the 2 slit holes at once. The conclusion is based on the QM theory, ie, the solutions of equations that QM produced, stated that there is an appreciable probability that the particle goes thru the 2 holes at once and this is why Physicists believe that in actuality, this is actually what happens (ie, the particle goes thru the 2 holes at once), however there is no direct experimental evidence only inference. This scenario is unprovable, because according to QM theory, if one attempts to measure which one of the 2 holes that the particle went thru, it means they only went thru one and not both holes, so there can never be any successful attempt to measure if indeed the particle goes thru the 2 holes when you're not looking (ie, no measurement), but when measurement is put in place tell if they go thru both, then one only ended up seeing that the particle only went thru one of the 2 holes but not both. Physicists have their faith in the equations.
This interpretation of QM which is what made quantum computing possible and it was late Prof. Richard Feynman who first recognized this and proposed the possibility Computing via quantum phenomena (ie, quantum computing) at a symposium at CalTech/MIT in the early 1980s. In classical computing or 1/0 bit of information is extended in quantum computing to qubit, where the notion of one or zero (1/0) disjunction disappears. One can say that the quantum bit (qubit) is both 1 and 0 at the same time where as in the classical sense the bit is only at one state 1 or 0 at a single point in time but not both 1 and 0 simultaneously. Qubit is a superposition of many states at once, similar to the double-slit-experiment's where the particle is at point A and point B simulataneously (ie, traversing thru holes A & B at once ).
There is a recent new theory that attempted to explain QM in a local manner because QM is a non-local theory (ie, non-causal & God-like phenomena) which is theoretically consistent with all the current observations of QM but avoids God-like physical explanation of being at 2 places at once. This new theory (TEW - theory of elementary waves) that a particle in the double-slit-experiment does indeed go thru one hole at all time, the problem lies in our theory and not our measurement apparatus.
It (TEW) suggests that the particle is guided by a pilot wave that originates from the detector (the back screen as in the double-slit-experiment) which impinges on the emitter (particle or electron source), and cause it to emit a particle which then the particle follows the path which was traversed by this wave (an elementary wave which is supposedly omnipotent in the universe, ie, it is everywhere). The particle went thru ONLY one hole (either hole A or hole B) which it continues thru and hit the point on the screen where the pilot wave (elementary wave) started from. The interference we see is caused by these pilot waves and the observed interference even the particles are shoot one at a time have got nothing to do with particles that go thru 2 holes at once, which has never been experimentally verified. If TEW is correct, it doesn't mean that quantum computing (QC) is impossible, it simply means that the design principles of QC have to be modified, since it is now not the superposition that attributed to QC phenomena, but it is now attributed to the pilot wave (which at the end does the same thing). TEW is only bad for mysticism where they have claimed all along that Quantum Mechanics had verified the existence of the paranormal/supernormal/supernatural which is completely bollocks. TEW completely throws any ties to paranormal out the window.
Anyway, I could explain a bit more but that is another topic of discussion.

Moore's Law, the observation that the number of transistors that can be placed on an integrated circuit has doubled every two years, explains the exponential growth in computing power that enables all the innovation we web-heads love so much. Futurist Ray Kurzweil argues that the exponential growth of computing power extends beyond the history of the integrated circuit, though. Exponential growth in computing happened as a result of innovations prior to the circuit board and it will continue after the integrated circuit's dominance has been surpassed, Kurzweil believes.
