Well, it don't know about the size of said proteins in particular but the amount resources needed is the reason there is such a thing as FOLDING@Home (like SETI@Home - voluntary, user-based cloud-computing)

So, it seems to be able to do THAT at least. It's a first step, let's see what the near future brings for d-wave.

D-Wave isn't building the kind of quantum computer that can run Shor's algorithm or whatever and crack RSA. The problems they solve on it are optimization problems using some kind of wacky annealing approach. Some people say that means they're not *real* quantum computers, but whatever, they can apparently solve some things faster than conventional computers so church-turing's your uncle I guess.

mathfag here, don't underestimate composite number factoring. It's actually a very difficult problem which is why it's used as the basis for some forms of encryption such as RSA.

Think about it for a second, how would you factor a number that's 500 digits long and only made up of two prime numbers (each hundreds of digits long)? Countless people have approached the problem and the best anyone has done so far. I have a geometric approach that seemed somewhat promising but I haven't worked on it much over the last couple years due to being a failure in other shit going on in my life.

>> No.4987686

Isn't there a good deal of debate over whether or not D-Wave computers are actually useful still? Their adiabatic method didn't sound like it could solve any generic problem assigned to it as not all of them could be reached by adiabatic transformations of the Hamiltonian. I wonder if this is why there hasn't been any news about Shor's algorithm being successfully implemented on the thing.

I don't really know what to think, there's a course right now on coursera called Quantum Mechanics and Quantum Computation that conveniently ignores this and teaches the quantum gate modell as the only possible one even though it is not practical in real life.

https://class.coursera.org/qcomp-2012-001/class/index

This company is at least 10 years ahead of academia in most aspects so who should you trust?

I think this is parallel to some other trends in science especially physics.

Like high energy physics, building large accelerators with limited potential to be usefull in everyday applications over low every which has every chance to be transformative.

Or what we did with fusion, trying to brute force it that even if it worked wouldn't change the way people got their electricity, over lower temperature approaches which have been mostly ignored and got very little funding.

>> No.4987745

>>4987708
Given that they are openly using a scheme that is known to be incomplete and useful only for a fairly small subset of problems, I would say that the gate model is still preferable since it is universal.

Cold fusion has never been credibly reproduced.

If anyone manages to reproduce cold fusion, it would be international front-page news.

This is probably because the adiabatic quantum computation will not work for all problems. While the adiabatic theorem is true, it will not work out if at any point in time, two levels become degenerate or staying in the true ground state violates some conservation law. There are a great many cases we are interested in where these two things occur and thus adiabatic quantum computing is not as useful as gate quantum computing.

>> No.4987782

>>4987757
by those standards it will probably never happen, since most journals automatically reject everything with cold fusion or anything similar in the title, the hundreds of results that somehow got published anyways won't be credible in your or the publics eye.

I've been on that website for years. It's just a bunch of research papers. I've even read one of the papers, it said (and I paraphrase):

Partially correct. Biology is "superior" as of now, but eventually we will surpass it technologically provided the human race survives for atleast another couple of hundred years.

Technology will not have the limitations of a human biological body. When perfected its only limitations will be those of the laws of the universe itself. But certainly we are very far from that. And in the big picture of technological advancements, processors reaching the computational power of one human brain will only be a miniscule milestone. We will surpass it very quickly, in a matter of a few years to a decade to reach the computational power of ALL the human brains that ever existed in one single processor and that will still only be the tip of what is possible.

To give you a perspective on how fast technology advances, we expect to have a processors a thousand times faster then what we have today by 2020. Going by Moore's Law we should surpass the human brain sometime in the middle of this century.

And in a few hundred years biology without technological enhancement will all but be extinct.

My bad. I thought it was clear.

A decade after reaching the computational power of one brain is what I meant. As long as Moore's Law holds true, which it has so far and is widely accepted, we should reach the computational power of one brain that is around 10^19 Flops by 2030-50 and if Moore's Law still holds true after this point we should hit 10^26 i.e the computational power of all the brains that ever existed and ever will in no more then a decade or two.

Cyborgs, eventually when nanotechnology sufficiently evolves but not immediately.
It is near impossible to predict all the implications since we are not taking into account the advances made in other fields away from computers which could takes us down completely new paths when combined with these super processors. A few conclusions we can draw are probably rapid early advances in the filed of AI and brain processor linking. The later, to put simply will lead to Matrix like real life simulations in regard to games, movies or whatever other things we wish to simulate. Communities will be formed in these simulations just like they were on the internet early on.
Predicting AI is a bit trickier. Early advances might see governments slowly incorporating it into controlling smaller networks/systems programmed to make decisions best suited for that system. It remains to be seen how rapid this incorporation is and how the public service industry reacts to these advances. It would be safe to assume most of the manufacturing and a lot of the customer service industry is replaced with some scale of AI.
