Does it annoy the hell out of you? I will admit that i dont get it, but i also dont get how some people get so excited about it. Maybe its just the theoretical nature that annoys me, i dont know. I'm always trying to find some videos to get me interested and they bore me literally to death. 
Anyways just wondering if i am alone on this. My IQ is vastly lower than the average GD member. |

Depends on if you subscribe to the conventional or electron current flow theory... Quoted:
Quoted:
Heck, I'm still trying to decide if it's holes appearing under electrons or are the electrons falling into holes.

its actually really fascinating. I had to take a few hours' worht of youtube rabbit-holeing until i finally got a good grasp on just the basics.
basically, something has different probabilities of being in different states. as usual, all probabilities add up to 1. but what is actually happening is that until its measured, its actually in ALL states at the same time! (superposition) but you never know what the state is untill you look for it. then its stuck in that state. thats the overall overarching simplistic point. then you have all the phases/angles to use to measure against. then entanglement. but quantum computing is what takes the cake. next on my list is to try to understand just how a quantum gate is able to take advantage of the effect of superposition in order to break crypto, etc. |

Or that the $.99 laser pointer, or the computer you're posting this from are impossible if quantum theory wasn't "real" either. |

There are a lot of people that get excited over watching sports when I find it boring.
I have disorder called dyscalculia and It effects how my brain processes math and numbers. I never even made it past simple algebra. If I didn't have this I would love to study physics or even quantum physics. |

It may have some unknowns yet, but a large chunk is solved, but not by clock cycles. They are making digital logic 'gates' using the qubit, but that is like using a digital computer to simulate an analog computer (which we do, a lot, since even digital is analog at some level). |

Then I saw little Tiffany. I'm thinking, y'know, eight-year-old white girl, middle of the ghetto, bunch of monsters, this time of night with quantum physics books? She about to start some shit, Zed. She's about eight years old, those books are WAY too advanced for her. If you ask me, I'd say she's up to something. |

I was in my senior year at college and had sent out my application to several physics graduate programs including one to Harvard who was chaired at the time by Nobel prize winner Sheldon Glashow. He had just given a talk at my college and I was determine to meet him afterwords and introduce myself as a candidate. Of course I needed a topic to engage him in conversation with so I made up a list.
When I met up with him after the talk he was rushing out the exit and down the hall to his car. I realized he was in a hurry so I had to discard my other questions and come up with something quick. After quickly introducing myself I asked him "How do we actually KNOW that quantum theory is the correct theory if it is so difficult to reconcile with gravity?" He told me to let him know when I find out. I never did get accepted. |

well thanks, but even that is a bit too advanced for me. i think i need more youtube.
but since youre here, I have a question: is entanglement even used or is it some component of quantum computing? or is QC done w/o entagled qubits? and did you read that article about chinese quantum comms system? whats that all about? as best I can tell, it was basically just using entangled pairs of qubits to be able to generate a truly random key to be used for encryption of both sides of a comms link. (as opposed to pseudo random which is used now). Do I understand that correctly? |

Anyways just wondering if i am alone on this. My IQ is vastly lower than the average GD member. I've studied physics and I did watch the TV show "Quantum Leap", if that helps. |

Quantum Computing is allowing all the various states to "be", and after filtering "The question"(program), the answer is The Answer(output). -- Super Super Super simplified. |

One of the most accessible writers on the subject of high end physics in general, is Chris Lee over at Ars Technica. He has a hilarious streak of self-deprecating humor in his writing. Fully admitting at times that he hasn't an idea of how a particular topic actually works. |
Try this to get started. Not a dig on ya OP, it's pretty good.

It's all made up in the heads of theorists. We're right about at the potential end of Moore's law for real, this time. That pesky quantum nature of electrons means that at this small of scale, they can just suddenly *wink* from, say a source or drain to the gate, and that throws wrenches in the works. |

Anyways just wondering if i am alone on this. My IQ is vastly lower than the average GD member. The single slit experiment blows my mind. You can actually reproduce it with a laser and a nail clipper held almost closed. I had to derive the diffraction pattern for a physics final once using hyugens principle. I was the only one to do so in the class. |
