| Been watching videos on the D-Wave machines. I understand the concept of qbits in superposition. What I don't understand is how in the hell you measure that. How are these calculations made? Explain it like I'm dumb, because apparently I am. |

There is no conventional way to explain them. I did a lot of research on them some time ago and its still confusing.
But basically they do their calculations on a super chilled microchip, or some shit like that. So in a normal computer you have bits and they are either 1's and 0's kind of like on/off. In a quantum computer you have on/off, off while on and on while off. You can have positive, negative and positively negative or negatively positive. Makes no sense eh? Thats because at the atomic level physics doesnt make any sense. A quark can seemingly be at 2 places at the same time. Or acts differently when observed. Because quantum computers work at an atomic level, they make no sense in a rational world. Some people believe that an atom has the ability to exist in several parralel universes at the same time and quantum computers use power from multiple universes. In other words, quantum computers are faster than they should be and there is no current explanation for it other than that its performing its calculations in multiple universes at the same time. Youtube has many videos on it but dont expect to come away any smarter. |

Quantum computers are like that retarded kid who when you ask a question to them, instead of saying yes or no, they just say maybe and grin at you all dumb. So you ask a different question that is still looking for an answer that will clue you in to the answer of the first question... and again they are all like "mmmmmm maybe". So you do that a bunch of times get frustrated then start rag dolling the shit out of the prick shaking them around, spinning then this way and that then they finally are too exhausted and fall down and spit out an answer somewhere in the framework of the questions you asked. Or... something like that... the shit's pretty complicated for being such a super simple premise. Oh, also, they work because "OMG it spins". |

I mean, was a guy just cooling chips to absolute zero for kicks? How do we usefully observe the quantum phenomena and (assuming I follow the split screen experiment) does observation affect the output? |

Don't get too excited, all they can do right now is minimize complex quadratic equations. We spent the entire lunch today trying to come up with something useful to do on one since we can get time on it. We got nothing. I'm not that excited, but you help a simpleton understand the how? |

I always have to google the Mandela effect because I forget what it means.

No idea. But they're being blamed for the Mandela Effect.

Watch this and see if it helps.

A solution space is defined as the value of many variables that define a system.
Qbits, which can take on any value, are linked to variables in the system. The collection of qbits, like any physical system, seeks and attains the lowest possible energy state, which corresponds the the values of the optimal solution in the solution space. Conventional computers (and people, too) tend to get caught in local minima in the solution space, when a better solution exists. Add to this the fact that the qbits can settle into this lowest energy state in a very brief time. |

Instead of 5-6 processing chips on a mother board, there are millions of processing chips on multiple mother boards running at the same time.
It has to be in a chilled vacumed environment so the chips and boards don't melt while working. At least that how I understand it. And the positions of ones/zeros or on/off can be one/zero/on/off all at the same time. Giving it quadruple times however many chips and boards are available for the computing power. Of course, I'm not very smart so I could be way off. |

Run it again and again? |

They use Heisenberg Compensators and Shröedinger declinometers in series to determine the qbit's state. |

[<snip> So how is one sure the observed result corresponds to the pertinent variables? Run it again and again? Yeah, that's exactly what they do. The final state doesn't guarantee the correct solution, it's just the correct solution is the most probable one to come up, so they run it over multiple times and the probability distribution will give the best answer. |
