This might start off cheesy but stay with it as it's a really good explanation of quantum computing using superposition, entanglement, interference, decoherence and fault tolerance. It's a whole new language!
It's the future of complex computing, especially mimicking big systems like life.

What a juxtaposition. Anything to do with the quantum world fascinates me, whilst computing is normally the ultimate turn off. I’ve seen a documentary about quantum computing before and found it really enthralling. Thanks for posting, I will definitely watch it.

I think it's slipped a lot of people by but the laws of physics are now gone due to the status these machines create.

It depends on whether you follow Einsteinian physics or quantum mechanics. One day, a grand unifying theory will merge these two sets of laws into something that will explain it all. Or not.

Surely, the laws of physics are the laws of physics? <iframe width="22.660000000000082" height="2.9200000000000017" style="position: absolute; width: 22.660000000000082px; height: 2.9200000000000017px; z-index: -9999; border-style: none;left: 15px; top: -5px;" id="MoatPxIOPT1_30693765" scrolling="no"></iframe> <iframe width="22.660000000000082" height="2.9200000000000017" style="position: absolute; width: 22.66px; height: 2.92px; z-index: -9999; border-style: none; left: 1074px; top: -5px;" id="MoatPxIOPT1_12256965" scrolling="no"></iframe> <iframe width="22.660000000000082" height="2.9200000000000017" style="position: absolute; width: 22.66px; height: 2.92px; z-index: -9999; border-style: none; left: 15px; top: 87px;" id="MoatPxIOPT1_84621464" scrolling="no"></iframe> <iframe width="22.660000000000082" height="2.9200000000000017" style="position: absolute; width: 22.66px; height: 2.92px; z-index: -9999; border-style: none; left: 1074px; top: 87px;" id="MoatPxIOPT1_25425822" scrolling="no"></iframe> We just haven't worked out what they are yet! |

Wow - Thanks for that, Martin, just watched it.
My brain hurts. Whenever I try and think about Quantum mechanics that happens!
I had no idea what quantum computing really was. I now have the barest smattering of an inkling.
The simple-to-pro multi-layer approach to the tutorial really helped me begin to get a feeling for it rather than hurling me into qubits from the start.
I can see that going from 1s and 0s to add extra possible states would hugely increase the computing power - I guess that's it in a nutshell?
But it seems amazingly difficult to do on a sufficiently large scale to make it really revolutionary.
Standout quote - "Things are gonna happen that we just can't foresee."
Exciting stuff.

My brain hurts. Whenever I try and think about Quantum mechanics that happens! I can cope with superposition - like Schroedinger's Cat being both alive and dead until the box is opened and the cat is observed. What blows my mind is entanglement. How does that work, then? |

You humans such a funny bunch quantum entanglement is a required subject at our primary schools, maybe another few years before first contact then  |

It doesn't have to make sense! In fact, if quantum mechanics does make sense to you then you need to found out more about it so that you realise that it doesn't make sense.   <iframe width="18" height="9" style="position: absolute; width: 18px; height: 9px; z-index: -9999; border-style: none;left: 5px; top: 72px;" id="MoatPxIOPT0_10944209" scrolling="no"></iframe> <iframe width="18" height="9" style="position: absolute; width: 18px; height: 9px; z-index: -9999; border-style: none; left: 836px; top: 72px;" id="MoatPxIOPT0_31134024" scrolling="no"></iframe> <iframe width="18" height="9" style="position: absolute; width: 18px; height: 9px; z-index: -9999; border-style: none; left: 5px; top: 463px;" id="MoatPxIOPT0_79273956" scrolling="no"></iframe> <iframe width="18" height="9" style="position: absolute; width: 18px; height: 9px; z-index: -9999; border-style: none; left: 836px; top: 463px;" id="MoatPxIOPT0_96564895" scrolling="no"></iframe>   |

Richard Feynman. Simply THE MAN.
I have many of his biographies and some of his lectures on VHS tape, too.

Please can someone help me?
I understand basic Newtonian ('common-sense') physics at the macro level (planets, cricket balls etc) and the micro level (Brownian movement etc). I can't say I understand much about the behaviour of particles at the quantum level ( let's say perhaps 10 to the minus 35) except it seems 'chaotic' to say the least, when particles can exist simultaneously as two separate states, and is distinctly non-Newtonian.
My problem is this: somewhere in the middle - between the micro/nano/pico level and the quantum level (let's say 10 to the minus 22) we must have particles/entities/energy levels on the border between the two, seemingly conflicting, states. What happens? Has it been observed? Where is the border?
Thanks....

There is no in-between really as everything we know is made up of these tiny multi-state particles at the quantum level. It's just that we have two theories that won't meet in the middle. It's our lack of understanding that can't get a match between the nano-level and the world we see around us that creates the artificial 'border'. One day, it'll all come together and we'll have a full understanding of how apparent chaos seemingly creates a more orderly structure above it.

Maybe the movie Forbidden Planet had the right idea ... "As though his ape's brain could contain the secrets of the Krell." Maybe a true understanding of the universe is just beyond our capabilities? <iframe width="6.78000000000003" height="6.78000000000003" style="position: absolute; width: 6.78000000000003px; height: 6.78000000000003px; z-index: -9999; border-style: none;left: 5px; top: 85px;" id="MoatPxIOPT0_19385951" scrolling="no"></iframe> <iframe width="6.78000000000003" height="6.78000000000003" style="position: absolute; width: 6.78px; height: 6.78px; z-index: -9999; border-style: none; left: 286px; top: 85px;" id="MoatPxIOPT0_94384621" scrolling="no"></iframe> <iframe width="6.78000000000003" height="6.78000000000003" style="position: absolute; width: 6.78px; height: 6.78px; z-index: -9999; border-style: none; left: 5px; top: 366px;" id="MoatPxIOPT0_15512577" scrolling="no"></iframe> <iframe width="6.78000000000003" height="6.78000000000003" style="position: absolute; width: 6.78px; height: 6.78px; z-index: -9999; border-style: none; left: 286px; top: 366px;" id="MoatPxIOPT0_80627794" scrolling="no"></iframe>  |

+1 A lot of people believe it used Shakespeare's "The Tempest" as its template. It was also the first movie that had a completely electronic soundtrack. It's also the name of a great little bookshop I used to visit, in Denmark St. before they got all super-store-ish. |
