When scientists describe the universe as having a size, they're usually talking about the observable universe. I'm absolutely shocked that quantum computers can be that powerful though. Are you sure there isn't a mistake?


IIRC, every time you add a qbit to a quantum computer it's power doubles. So if you have say a hundred thousand qbits, that's a hundred thousand doublings from one qbit. I may be wrong on this though.

What difference does it make?

And some of us predict we will get to the point where we create planet-sized computers (at least of the quantum kind or something more complex)... Surely, that's way more the 250-qubits required to stimulate the Universe... can anyone think of what we can do with all that processing power?

Something like that...

Even if the number of equivalent bits is the same as the number of atoms in the universe, actually simulating all those atoms would require yet more bits for the physical interaction.
NO!

But you don't need to simulate every atom or quantum particle to create simulation of universe.

If you stimulate every atom, you just created an Universe or at least have the processing power to create one.

I recall someone claiming that it is very likely that we are living in a stimulated Universe.

I'm curious to know at what rate qubits will develop in size. By that I mean how long it will take to get from a three qubit QC to a 250 one and beyond.

I believe there was another post recently showing that the progress of QCs is currently following the same trend as traditional computers (I.e.) Moore's law
All right, brain. You don't like me and I don't like you, but let's just do this and I can get back to killing you with beer.

Think about this:
Mankind has had digital technology since about 1943 which is only 69 years. Not even 70. Think about that, and then think that in 70 more years we will be starting to make some really amazing super computers.

Then think about this. It is possible for an alien race to have 3-5 billion years more experience with digital technology now than we have. How long ago did life start on Earth? Well about 3.8 billion years ago. Now wonder if we are in a simulation. The universe could be expanding into nothing because it hasn't "loaded yet".

I don't think we are in a simulation because why would someone keep a 3.8 billion year old computer around? Still, interesting to think about when your bored.

I think it simulation may be lot faster, you just press one button and it goes million years each second. By the time tentacled alien gets his coffe dinosaurs die and humans reach Moon.

There seem to have been quite a few breakthroughs lately, so let's have a dedicated thread.

Quantum breakthrough: Scientists generate qubits within semiconductors

By James Holloway

04:09 March 26, 2012

A significant step on the path to quantum computing has been taken by an international team of researchers applying a 22-year old theory. They have succeeded in creating quantum bits within a semiconductor for the very first time.

Can you please provide a list of expected breakthroughs quantum computing could provide? Does quantum computing allow for accelerated results in particular areas of research at the moment?

Researchers claim quantum breakthrough

Researchers say they have designed a tiny crystal that acts like a quantum computer so powerful it would take a computer the size of the known universe to match it.

On the other hand this thread needs to be pinned as well.

What is true, just, and beautiful is not determined by popular vote. The masses everywhere are ignorant, short-sighted, motivated by envy, and easy to fool. Democratic politicians must appeal to these masses in order to be elected. Whoever is the best demagogue will win. Almost by necessity, then, democracy will lead to the perversion of truth, justice and beauty. -Hans Hermann Hoppe

Yet, we can't even see a structure that consists of 300 atoms unaided! Imagine if we manage to increase the number of atoms so that all of them make up a quantum computer the size of a smartphone or even a laptop! How many times 2 to the power beyond 300 atoms is that? The human brain makes up an impossibly fraction of the total number of atoms in the Universe so this means if a quantum computer using this technique is same size as the human brain, we'll be so left far behind as to be considered an insignificant nuisance (even less than a speck) to the new super-intelligences! Crazy if reality proves this theory right!

I can't wait until they actually build that thing. Although I probably won't be alive when it happens haha
