Quantum mechanic claims that quantum computer must be possible to build, but unfortuntly quantum computers don't working... Quantum mechanic don't have any evidence about completnes and possibility to build quantum computer and that for simulation quantum physics need exponentional computation power. So quantum mechanic is hypothetical theory. Some things in quantum mechanic are proven and some - not. Why those unproven things are included in quantum mechanic theory? Why there is tryes to build quantum computer if there no proff about concept according to which quantum computer must work? Should we try made all things, which we can imagine and which don't match with logic (multiuniverse, exponentional speedup...)?

No, some parts of quantum mechanics are hypothetical. The vast majority is not. The CPU in the computer infront of you is designed and built using sections of quantum theory, evidence that those sections work.

Absense of proof is not proof of absense. Noone has disproved the existence of God simply because there's no evidence he exists. And given the vast amount of evidence for the majority of quantum mechanics, there's even less reason to deny the other parts of quantum mechanics.
QUOTE (DavidD @ Feb 28 2008, 09:54 AM)
Why those unproven things are included in quantum mechanic theory?
Because they are the invitable result of the axioms of quantum mechanics. QM has a handful of axioms and it predicts thousands of phenomena, most of which have been experimentally verified.
QUOTE (DavidD @ Feb 28 2008, 09:54 AM)

That's like saying "Why do an experiment to test a theory if there's been no experiment to test the theory?". Building a working quantum computer would be evidence that it works. And they have done. You've been shown evidence of such a thing. I've been to talks, from physicists researching the area, about how they've built quantum computers.
QUOTE (DavidD @ Feb 28 2008, 09:54 AM)

Quantum computers are the logical implication of the axioms of quantum mechanics.

Why don't just remove hypothetical parts from quantum mechanic? Ofcourse quarks also are hypothetical particles, but they more or less fit in with leptons and can somthing explain. But hypothetical part of quantum mechanic I doubt that can somthing explain.

So I can take and connect some quantum dragon, which living in atom to quantum mechanic and then claim that it is part of quantum mechanic.

Bonus question: Does exist evidence that Pauli matrices exist?

in page 89: http://www.tau.ac.il/~tsirel/Courses/QuantInf/lect7.pdf
is saying that for simulation in 3 dimensions one quantum particle with 100 point for each dimension need 100^3 bits. And for simulation 5 such particles need 100^15=10^30 bits. For classical computer it is imposible. Now imagine that there is five planets and each planet have one Moon. Each planet has positive charge and each moons has negative charge. And all those 5 planets are enough nearly to each over to atract each over with fields (of plus or minus charge). And for each planet and for each moon is 100 point for each dimension. How much bits need to simulate this 5 planets with 5 Moons? I think that also need about 10^30 bits (or operations...).

Because they arise from portions of QM which are known to be true. It's like saying you know all of the technical information about a gun, but don't believe it'll kill someone if you shoot them in the head with it.

Even if quantum mechanic behave acording quantum theory in some conditions it's still don't mean that is possible to build quantum computer, becouse thermal noise may be stronger...

No, they have actually been built and have been used to compute the solutions to simple problems. You're denying the existence of well documented things.

Have you ever been to Beijing? Do you deny it's existence simply because you haven't seen it with your own eyes?
QUOTE (DavidD @ Feb 28 2008, 03:41 PM)

Because that's like saying "If we haven't seen it yet, it doesn't exist". When Einstein formulated general relativity there was no evidence for it over Newtonian physics. By your logic, he should have chucked it in the bin because it was all, at the time, hypothetical.
QUOTE (DavidD @ Feb 28 2008, 03:41 PM)

No, deep inelastic scattering proves that neutrons and protons have point charged within them which couple via a force other than electromagnetism or gravity. Quarks also explain all mesons and baryons. Quarks were a concept developed because experiments said they existed.

But then you're an idiot.

No, because this is not an implication which is derivable from the axioms of quantum mechanics.

The results of quantum mechanics cannot be derived from Newtonian physics. Hence you cannot say "Newtonian physics explains quantum mechanics". Just as you cannot say "Quantum mechanics says dragons live in atoms".

Do you even understand how logic works?
QUOTE (DavidD @ Feb 28 2008, 03:41 PM)
Bonus question: Does exist evidence that Pauli matrices exist?
*sigh*

You and I have already discussed this. Matrices are mathematical objects, they no more exist in reality than d/dx differential operators do. However, they form structures which, when certain physical quantities are assigned to the structures' components, which mirror the behaviour of certain physical systems.

For instance, the spin of electrons around atoms or quarks in hadrons form structures which are seen in Pauli matrices. Angular momentum also forms a structure like the Pauli matrices, ie if J_i is the i'th component of the angular momentum vector J = (J_1,J_2,J_3) then these have the structure [J_i,J_j] = ε_ijk J_k. The Pauli matrices, σ_i, form a structure [σ_i,σ_j] = ε_ijk σ_k. Thus you can describe angular momentum behaviours using the Pauli matrices.

Another example is that the Lorentz transformations in relativity form the Lie group SO(3,1). The Lie algebra of SO(3,1), so(3,1), is the direct product of two copies of the Lie algebra of SU(2), su(2)xsu(2). The generators of su(2) are precisely the Pauli matrices. Thus you can describe space-time transformations using the Pauli matrices.

All of these are experimentally verified, space-time transformations like rotations and boosts transform like that and the spin of electrons in magnetic fields transform like that.
QUOTE (DavidD @ Feb 28 2008, 03:41 PM)

People can answer, I've answered you in this thread and I've answered you in other threads. You just don't want to listen.

This and the fact you seem to think you understand Pauli matrices but obviously don't, make me feel justified in calling you are complete idiot. A staggering fool. A delusional mor0n.

OK, Pauli matrices seems describing spin very well and was experimentaly verified...
But I can't understand how to create entangled electrons or atoms? Entangled photons are created when blue photon of light bunching into crystal and then going out two red photons. Besides, Alphanumeric, you never write about entangled electrons.
"In the1990-2000, several experimentalists showed that entangled photons generated
by non-linear crystals could stay entangled for distances up to 10 km." So photon entanglement is proven, but how about electrons or atoms (or maybe nucleons, or bosons)?
QUOTE
No, they have actually been built and have been used to compute the solutions to simple problems. You're denying the existence of well documented things.

If you more believe in documents than in brain, then you are an idiot. What's a point to claim that they working if they working exponentionaly bad? You probably don't analise what is wroting in those documents, more deeply?

"Since one electron produces several photons instantaneously, such photons are
entangled according to Quantum Mechanics. Being statistically spread in a cone,
entangled photons can hit several samples, swap their entanglement to nuclei or to
atom electrons. Electron accelerators are thus efficient tools for irradiating
thermoluminescent materials where entangled electrons can be stored."
http://arxiv.org/pdf/quant-ph/0611109
"Recent work with electrons in magnetic materials show that at very low temperature
the electron motion does not stop [14]. Electron spins are entangled in pairs and their
innate bond with one another keep them from freezing, contrary to what classical
physics predicts" - Can't understand how electrons are entangled and what conditions need to make them entangled?
"Furthermore the entangled electrons seems to be resistant to decoherence, that is
the collapse of their entanglement, since samples, co-irradiated several months prior
to the experiments reported here, still gave intense signals. An extremely large
number of single electrons in one crystal are entangled with electrons in the other
crystal and “stored” in relative decoherence free space of impurity traps of the
crystals. It appears that the ion traps are behaving very similarly to QED quantum
cavities." - If Ion trap QC dosn't working, why I should believe in entangled electrons?

This citated make me believe in entangled electrons at 70%:
"The reported experiments are a practical implementation of the entanglement
phenomenon of Quantum Mechanics. Two particles are said to be entangled when
they are emitted simultaneously by the same atomic wave function, for example;
photons emitted by a nucleus, or an electron, and the photons temporarily form an
interactive interference pattern with one another. Such particles are quantumconnected
to each other and interaction with a measurement system by one of them
is “sensed” immediately by the entangled counterpart. Entanglement can be
swapped between two particles and two other particles. Entangled particles, such as
10
electrons, can be “stored” in ion traps or impurities within thermoluminescent crystal
lattices and remain isolated from environmental decoherence effects in the traps for
considerable amounts of time. Electrons can be forced to leave these traps and then
drop down to their respective ground state energies in the crystal lattice by thermal
heating or by stimulated luminescence. An entangled electron dropping out of its ion
trap will go through spin transitions which affect its entangled counterpart electron by
reason of spin conservation laws such that it becomes favorable for the counterpart
electron to exit its trap as a result, emitting some light while dropping to ground state,
at whatever distances the traps are located from one another. Since traps can be
entangled even though present in separate crystal lattices, such samples can be
separated by a large distance and the entangled electrons still be connected until
perturbed by thermal heating of the crystal lattice containing one of the trapped
entangled electron pairs. It appears that the trapped entangled electrons escape only
at discrete and unique temperature values, thus allowing the same glow curve
response (although much less intense than the heated crystal) to be recorded for
each non-heated thermoluminescent crystal when the temperature of the heated
crystal lattice is increased and decreased. This experiment amply demonstrates that:
- Bremsstrahlung gamma ray or X photons are entangled,
- The entangled photons can transfer their entanglement to particles (electrons)
- swapping entanglement between particles is possible and does occur,
- entangled particles can be “stored” as wave functions in ion traps that behave
as QED cavities within thermoluminescent materials,
- environmental decoherence appears extremely feeble within ion traps
containing entangled electrons since the heating and measurement
experiments were conducted over one month after co-irradiation of separate
TLD chips,
- entangled electrons appear to exit the traps only at very discrete and
characteristic temperatures during temperature increase and not in accord
with the Arrhenius equation which dictates that ordinary electron traps empty
as a function of a continuum of release temperatures. This is a significant
finding of this experiment which should provide quantitative clues for the
interaction mechanisms involved in entangled electrons within ion traps
- slave chip (non-heated entangled counterpart crystal) glow curves correlate for
the crystal lattice temperature increasing and then decreasing via cooling
(temperature turn around point) in a very symmetrical and systematic way,
- quantum liaisons can be established between locations situated 8,182 km
apart."

Photonic quantum computer can't be made, becouse even entangled shamngled photons don't want talk to each over, becouse very hard to connect them together in 3D space. QC with atoms or electrons dosn't work, becouse of thermal noise either of imposiblity manipulate electrons in way, which quantum mechanic predict, when electrons are entangled.

Yo, I read that to entangle two atoms or electrons is very hard, becouse they entanglement is through photons so need everwhere mirrors around and this sounds shitly. And thermal noise will make deconherence faster than photons through mirrors will do them job. Also entangled(?) atoms talking through phonons (high frenquency sound), what is very strange. All this problems with entanglement of two atoms or electrons sounds very imposible. So I think 50% that maybe entangled elctrons was been demostrated.

Pauli matrices invented for describing spin (of electron or prtoton, neutron) and they have nothing to do with entanglement. I only don't know does pauli matrices describing spin in 3D or not, but they work only with single particle and this means, that entanglement between two atoms or electrons wasn't doen. On the over hand entanglement between two photons was maded, but quantum computer with photons somewhy can't be builded (I am not sure, this is becouse need exponentionaly many gates or becouse need that photon interacts more with each over than just that they be entangled...).

No, su(2) was described centuries before Pauli came along. Cartan did a complete enumeration of simple Lie algebras long before Pauli worked out a physical application for su(2).

Pauli got his name attatched to them because he took the mathematical concept of su(2) and realised it had physical applications. Just like Lorentz realised that SO(3,1) was the symmetry group of Minkowski space-time.

Still not grasping it, are you? Photon based quantum computers have been built. You seem to think that because BIG (ie lots of bits) quantum computers haven't been built that ANY number of bits is impossible. Wrong! Quantum computers with bits less than 8 have been built. It's known as 'proof of concept'. The concept of quantum computers works, experiments prove it. Getting large scale quantum computing is different.

It's like saying "A big fire isn't hot" because you've only ever seen small fires, which you accept are hot.

Only dreams, but no working quantum computer.
Did you miss the one which said "using methods for quantum gates that have already been experimentally implemented"? Did you bother to look at any of them or did you just reply without even thinking about it?

You're obviously not interested in physics, you whine about concepts you don't understand and you refuse to look at evidence. Why do you even bother coming to this website if all you're interested in is hearing yourself talk? Do us all a favour and stop posting. You can just sit at home and speak outloud. At least then you're the only person who has to be exposed to your ignorance.

I say this, just becouse to made more easy to you understand, that they proffs is TOTALY BULLSHIT!!!

But not proven. If 58% or somthing working instead classical 50% it don't proves that those gates working. And if gates implemented then what stoping them from building quantum computer with 2 qubits?
QUOTE
Photon based quantum computers have been built.

Show me PDF, please.
QUOTE
You seem to think that because BIG (ie lots of bits) quantum computers haven't been built that ANY number of bits is impossible.

NO, wasn't build even 2 qubits quantum computer.
QUOTE
Quantum computers with bits less than 8 have been built.

With exponentionaly bad qubits.

It's known as 'proof of concept'. The concept of quantum computers works, experiments prove it.

Experiments nothing had prove. Press - yes.

Alphanumeric, who you are idealist or materialist? If you are idealist then you probably believe in Manyworlds, exponentional speedup, or somthing like this, many dimensions and that our world isn't classical, but quantum or whatever. I am materialist and believing that our universe is 3 dimensional and working accoring classical physic (with smallest particles like in my theory, for example). So I don't believing in exponentional speed-up becouse it's violates laws of classical physic.

Does there is proves about superposition of excided and ground state of atom?
Does there is nontrivial (90-100% match with experiment) prove about entangled atoms or electrons?
Phonons indeed can't create superposition or entanglement.

Quantum mechanic is indeed noisy and thus shrodinger equations are wrong about exponentional wave function, which describing quantum particles and they interaction.
