GeneralQuantum computers and qubits revisited.... [modified] PinprofessionalJeremy Falcon3-Aug-14 8:43 
Since this is the future of computing, it's time we all started to learn about it. Most people that try to explain it fall short (even Microsoft). So it would be cool to get some of the brains on here to take this study further. So, here's my take on it, so far.
 
This river runs really deep folks, but let's start with just the concept of a qubit. It's logic defies traditional logic in that it has three states: yes/on, no/off, and indeterminate.* However, when measured it can only show two states: yes/on or off/no. Here's a traditional wtf definition of it that few can make sense of...
 
Quote:
Bits, either classical or quantum, are the simplest possible units of information. They are oracle-like objects that, when asked a question (i.e., when measured), can respond in one of only two ways. Measuring a bit, either classical or quantum, will result in one of two possible outcomes. At first glance, this makes it sound like there is no difference between bits and qubits. In fact, the difference is not in the possible answers, but in the possible questions. For normal bits, only a single measurement is permitted, meaning that only a single question can be asked: Is this bit a zero or a one? In contrast, a qubit is a system which can be asked many, many different questions, but to each question, only one of two answers can be given.

 
So, to make this more clear. Let me explain the quantum theory outside of the realm of bits. Think of it this way, what makes a joke funny, when someone gets it, understands it, and agrees with it right? And to agree with it that person must have had an experience in life that coincides with that joke; otherwise they wouldn't get it. If it's a joke a only select few get, does that joke become not funny because most people don't laugh? Or is it funny still because at least a few do? The answer is both! And if you want to store data on whether or not the joke is funny, you have to store both true and false, because the "truth" is relative. Now, the joke may not be funny to you (an observer) but it is still funny to someone and thus funny and not funny at the same time.
 
As such, an answer to the question can only take form when the question is asked and the answer is dependent on the observer or person / machine asking. Does this make more sense to peeps now? There's a lot more I'd like to talk about on the subject if there beez some folks here into it.
 
* Edit: Added a strike-through over the part that was crap.
