The brain is not a quantum computer. It is an analog, highly parallel image processor.

It's not that I don't understand quantum computers, it's just that I have never heard an explanation of what one is and how it works. I venture that no one posting here has either. ALso, so how would you write a program for it.

The brain is not a quantum computer. It is an analog, highly parallel image processor.

Well William for a 20mhz parallel computer our brain's seem to be able to do what a gigaflop parallel computer can't so i'll ask you to now explain why that is so please

Hey Will'....your in the docks here. As far as I'm aware our brain is classed
as a quantum computer.

The brain is better at some tasks and the computer is far better at others. Today I taught graduate stats and used statcrunch on a computer to do in seconds what might take a person with pencil and paper half a day or longer. This evening I cooked a splendid dinner which I don't expect to see a machine do in my lifetime. Perhaps we should resurrect the old argument "can machines think"? In time the distinction will blur further.

I did research on artificial neurons a long time ago. Even took graduate courses from Ross Ashby (Design for a Brain) and Heinz Von Forster of early Cybernetic fame. Mostly, I wound up debunking those who thought what they were doing was different from Boolean Logic and circuitry. We think we know roughly how a neuron works and that there are perhaps 10^12 of them in the brain. But each of these may have a thousand synaptic connections. We worked on Threshold Logic but though we could build simple logic circuits you could do the same with a few flip-flops and counters. No one was able to take these structures and build anything like a brain nor develop a logic to assist in the design. Look at the "Perceptron" to see how far they got. Also, the Avian retina was reproduced functionally in logic (edge detectors, bug detectors etc)

I don't know how the brain works, nor does anyone else. It is processing electro-chemical waves,images and storms via slow, chemical reactions that may resemble single sideband frequency modulation for transport. Where is the screen upon which we play consciousness ? How does memory work and where? Most brain research is at a macro level we map electrical activity in different areas of the brain and attempt to associate it with certain moods and experiences.

My daughter is a recent Neuro-science graduate and there are neurologists but they are concerned with manifestations of macro brain functions and not how the hardware, logic and interconnections work. So I don't know how a quantum computer works and I don't know how the brain works and If I did I would likely be the first.

I do know how a digital computer works and how to build one and how to program it to do amazing things. The brain remains better at many things now--it will not always be--perhaps a quantum computer will speed up this process but first we have to have one that offers an advantage over todays vastly sophisticated computer architectures and programs.

I apologize for this discussion as I note that this thread was about warp drives. I don't know how those work either so I will await a working model with baited breath.

The advantage these Quantum computers would have was the ability to think,
something the standard computer can not do. When I read the article on
the quantum computer, somewhere around 9 years ago, an example was given
regarding what the quantum computer could achieve. The example was set aginst
the simple process of completing a jigsaw puzzle. The article stated that
with the most powerful conventional computer this task would take that computer
around 360 million years to complete. The average intelligent human would take
about a day to achieve this task, the quantum computer around 4 minutes.

I still believe there is not yet a real digital quantum computer, despite D-Wave selling two of them fore ten million dollars each. They might be analog computers, a kind which still exists, even if nobody mentions them.

I agree with you Tullio 100%
Somebody is foolish enough to part with there cash as the saying goes there's a sucker born every day .....lololol

Quantum computers are never digital.

What about Peter Shor's algorithm?
AFAIK the only customer of D-Wave is an armament industry which builds costly Stealth aircraft for the US Gov and others (including the Italian Gov unfortunately).
Tullio

Certainly D-Wave has a working device, but no one is sure if it has much in the way of quantumness associated with it. Now, if these results require that the whole system is fully entangled (quantum entanglement) and fully coherent, then expanding the number of qubits to prevent level crossing may come at such a cost that solutions to NP-hard problems remain out of reach


or in other words it has yet to be proved it works

---

Do you even know what Quantum entanglement means? I Doubt it.

I think that's the state my brain cells are in when I wake up some mornings....LOL.

---

"Time is simply the mechanism that keeps everything from happening all at once."

No I guess I don't know what quantum entanglement is .

I am not going to get into another word game with you .

Google are in partnership with D-wave and Lockheed martin

if I didn't know much about Quantum mechanics I would not have understood what the article was saying but you can tell us what Adiabatic Qbits is then

if you can't explain it then take your own advise

---

As you said I copied the article from a web site but to explain it I would have to put the whole article up and the mathematical problem he was talking about
and you have already advised me that I should not do that right !

What I will tell tho is I was looking for a layman's explanation of your post about "Adiabatic Qbits". level crossing is one of the problems with it

so I say again take your own advise

I'm shore Tullio would be understanding it after all he is a retied astronomer and why you wish to discredit him or make fun of him is beyond me

---

I think that teleportation of photons is already being done. But they are massless particles.
Tullio

An interesting particle is the photon, especially when split for each half
manages to stay in communication with the other.

Yep Tullo is correct it is Qantum Entangled yes there spooky action but Einstein didn't believe it he said God doesn't throw dice

However resent experiment with Teleportion in Hawai proves it does happen and teleportation would invole 3 protons
Again you need to watch Professer Brain Green doco Fabric of the cosmos episode 3 Qantum Leap

This one of my earlier posts so please tell me again that I don't understand what Quantum Entanglement is even if I could not explain it scientifically

---

umm you shore because i'm shore he said to me he was he may also be a physicist he didn't tell me that

---

good night everyone very late here i'll leave the ummmmm to debate things with you guys

I have cooperated with an engineer who is doing research on quantum computers and we published an article in 1996 on the Italian version of MIT Technology Review. Then I used my computer to run a BOINC project, AQUA@home, where AQUA stood for Adiabatic QUantum Algorithm. The project was started by D-Wave and I learned something about this firm from its message boards. Then they sold a quantum computer (D-Wave One) to Lockheed Martin and the project was abruptly terminated. I am still following the field especially on "Nature" magazine but I have also downloaded lectures by David Deutsch of Oxford University on the theoretical foundations of quantum computing. I have learned a new aspect of quantum mechanics from these lectures.
Yes, I had read about Google reaching some agreement with D-Wave, but the only computers they (D-Wave) have claimed to have sold are those sold to Lockheed Martin.

Here's my take on Quantum Computers and what appears to be mistaken implications and hype. We all know that the speed of a computer is limited by the energy that it takes to switch states and the distance between logic gates which has been shrinking steadily somewhat in accord with Moire's law. It is thought that to go much faster we will have to eventually get down to the atomic level--hence the use of the term quantum computer. There are of course other considerations for computing speed with today's technology such as pipelining, parallel processing and use of implicit parallelism in computer programs.

Another boast is that a quantum computer can be in many states at once--really ? how do we know which state is the correct one ? For my money an electron is in a plus spin state or a minus. If you like the Schrodinger cat idea of neither state then maybe you have three states --but don't look.

It is stated that a digital computer can only be in one state at a time. While that is true 64 or 128 bits can be processed at once and this is only limited by word structure and packing in so many floating point representations.

So I say. Lets see the hardware, logic, and programs that can make use of the so called quantum computer.

Yes Einstein did say that God does not play dice with the Universe,
to which someone replied,
Stop asking God.

I have no idea what you're babbling about half of the time, if not more.

So in the vein of babbling i posit this,
at the moment of the Big Bang,
all of space, time, energy, and maybe no matter, was condensed within a Planck Unit of Space-Time and here we be.
Surely all of space-time is entangled on a quantum level given its origin.
And what ...i have no idea.

Please enlighten me.

Morning GF I see you waited till I went to bed before posting your message .you statement as usual is rubbish you don't understand the beginnings of the Universe .
Was there matter in the first unit of Planck time ?
Do you even know what a Planck unit of time is ?
How can protons be Entangled if there wasn't any matter to Entangle ?

WTH is your problem?
Glenn clearly has trouble expressing himself to us, but it seems pretty clear he has tried to learn some things, pass on what he's learned, and then learn some more, including from us.
Aren't you the guy who's profile said a month ago that you're from Zambia and how you were going to stop posting and crunching, followed by a brief lament about those who have disappeared?
Well, keep it up. Maybe you can help a few more disappear.

I tend to agree with you on a FTL system when they get the LHC going again and find out how and the Higgs field does what it's suppose to do there mite be a way to get around it.

I recently heard of a experiment that some boffins where doing measuring how fast neutrino's where traveling from I think it was a galaxy and they found one of two neutrino's had travelled faster than light and has thrown a spanner in the works for physicists and no I don't know how they measured this but does make you think that FTL mite be possible in a another couple of decades .

Tullio have you heard anything about that and weather they stuffed up there calculations ?
