Boffins lay out 'practical requirements' of 'realistic' QUANTUM COMPUTER

Destroy All Monsters

Our computers use the binary system of 1 and 0s. Quantum computers use qubits (quantum bits), which can exist in "superposition", meaning that they can be a 0 or a 1 and everything in between... simultaneously.

NO!

"The state of the qubit is a complex-valued probability distribution over the state space { 0, 1 }"

Isn't that clearer?

Re: Genuine question

You will be able to

1) Factorize numbers for fun and profit

1.1) Probably do quantum crypto stuff on the side to alleviate 1)

2) Do quick searches in a database (faster than using a search tree)

3) And simulate quantum processes without exponential slowdown. THIS IS THE MOST IMPORTANT PART as it means advances in material science and deeper understanding of how molecular interactions actually work.

Needs better explanation

With enough qubits, a quantum computer could therefore represent an awful lot of states simultaneously. If you can then ask the quantum computer the right question, its waveform should collapse into the answer.

With the answer given having a certain classical probability of being correct.

The quantum computer therefore – in theory – lets you get a complex answer in a single operation, rather than having to step through lots of iterations, as in a classical computer.

Only for the following algorithms:

1) Factorization

and

2) Searching in databases

All the other classical turing-machine algorithms have to STAY classical.

Re: "Blind, drunken Gods, swaying to the sound of mad piping...."

Am I wrong?

Yes. You seem to be mix this up with more oriental approaches like Zen Buddhism and things like that.

(I still hope to see Frank Herbert's Zensunni religion before I log off; it would be weird, but the human mind is malleable and can pull practically anything out of the hat as long as verification of it can be left as an exercise...)

"Blind, drunken Gods, swaying to the sound of mad piping...."

Further perusal of Jimbo's Excellent HTML Store™ revelas that...

Gnosticism presents a distinction between the highest, unknowable God and the demiurgic “creator” of the material. Several systems of Gnostic thought present the Demiurge as antagonistic to the will of the Supreme Being: his act of creation occurs in unconscious semblance of the divine model, and thus is fundamentally flawed, or else is formed with the malevolent intention of entrapping aspects of the divine in materiality. Thus, in such systems, the Demiurge acts as a solution to (or, at least possibly, the problem or cause that gives rise to) the problem of evil. In the most radical form of Christian Gnosticism, the Demiurge is the "jealous God" of the Old Testament.

So I think there is some leeway in those texts from the sandy lands.

Which ignores the fact many IIS server admins also try to hide their servers' identities as well

RESPECT THEIR SECURITY-FU! No wait. Why lose time with inanities like that? Oh well...

Indeed, many IIS servers run on corporate intranets and therefore are not visible on the Web at all, making IIS's real share of the webserver market even larger than the Netcraft survey suggest.

Massive news in the micro-world: a hexaquark particle

Destroy All Monsters

Holmes

It was Gell-Mann and Zweig who first introduced the concept of quarks in 1964, not Freeman Dyson.

Well, Gell-Mann pissed all over the idea at first and gave believers a hard time and some righteous belittling - he was sure "quarks" were only a mathematical neat way of expressing the nucleon behaviour. Apparently this is also where the name "quark" comes from - he called them "quirks", which sounded like "quarks". None of the Finnegan's Wake tall story stuff.

Once experiments came in, he decided to retcon his attitude on the actual existence of quarks. Such is life in the physics community.

Re: Neutron decay

I am sure I can be wrong. However, these ideas are not from me, they are a rather self-consistent model of how it works created by thousands of people each more brainy than myself. I can't compete with that ...

Heisenberg believed that the exchange particle involved was an electron (he did not have many particles from which to choose). This electron had to have some rather odd characteristics, however, such as no spin and no magnetic moment, and this made Heisenberg's theory ultimately unacceptable.

The binding is done via meson exchange, right? I remember that Yukawa came up with that idea. Note that if the neutron *could* decay in a stable nucleus, you *would* see it as there is always a diagram in which it decays immediately before any exchange happens (and it is bound to be advertised to the rest of the universe as such, i.e. "observed"). So energy constraints, like program contracts and assertions, are strong.

Anyway, today we have Lattice Quantum Chromodynamics, and the first Google result that comes up:

Re: @dan1980

it's a tiny ball of wibbly-wobbly quarky-gluony ... stuff

More like a Feynman diagram of improbable depth and complexity (think all possible interactions on overhead slides, layered on top of each other, with lesser probability the more complex the diagram is); like a a thin shell over a reality that is so alien and abstract in comparison that merely contemplating it would damage the sanity of the ordinary person! The most merciful thing in the world, I think, is the inability of the human mind to correlate all its contents...

Re: Neutron decay

More likely they still decay, but the free electron is quickly bound to a nearby proton, turning it into a neutron. From the outside it would appear that the neutron is stable

Absolutely not!!!1!

Your physics intuition only competes with your lack of google fu.

The reason that neutrons do not decay in stable nuclei is because doing so would result in a nucleus with HIGHER energy. And this is forbidden by a Brussels decree!

Why is Turing trolling so intelligently?

an average interrogator will not have more than 70 per cent chance of making the right identification after five minutes of questioning

It took me a full two minutes to ascertain that this means the "pass" criterium is indeed that more than 30 percent of the people shall fail to identify the machine behind the terminal as being, indeed, a machine after five minutes.
