Not according to D-wave systems in Burnaby British Columbia, Canada.

They have a free webcast scheduled for February 13 of a demonstration of their quantum cpu.

D-Wave Systems, a hardware developer headed by 34-year-old theoretical physicist Geordie Rose, has issued an open invitation to all technophiles to become "an eye witness to history" at the live-link, Feb. 13 launch of the company's "16-qubit" Orion supercomputer. And the demonstration of D-Wave's "technological first" will take place at a site equal to the company's portentous claims -- the Computer History Museum in the heart of Silicon Valley

I can not help but wonder that once these things start to become commercially available just how fast they will improve in both processing power and speed.

Hopefully this will be the first of many new developments in the Computer Industry that is moving far faster than the current Major Software Developers are capable of moving at and will put them back to the fringe community where they belong.

Speed can be dangerous.... CD drives spinning too fast blow up cd's what of a hard drive spinning too fast?

What about speeding up ALL the components of a PC?

by jaqui

systems with these will be an inducement to mainframe based computing though.

"16 cpus fit on the head of a pin, but requires a refrigerator sized cooling unit with liquid helium for cooling"
definately not a home system. nor a viable desktop system.
the heat control needs to be seriously addressed to bring these chips out of a big iron system.

by jmgarvin

I've got one of those in my car ;-)

However, heat is an issue as well as software development. I'm also curious how they over came the whole Schr?dinger's Cat thing.

by jaqui

about what os they are using and what efforts if any they are putting into getting any open source os working on it.

Lucky me, they are a short trip on public transit from here. :D

Their second public display is also local so I might get to attend in person.
[ I'm seriously concidering applying to attend, the cost is the issue ]

Since Quantum Mechanics, and now Computing go back around 100 years now, and so many people have been contributing to that field rather openly, it would be hard to make it propritory.
(Although, I think Enistein did have his ideas patented... ?:| Just as long as it get anywhere near Redmond...)

by dawgit

In order to achieve any computing at all, (*1) variables in a state have to be introduced. Hense; the Dead or alive little kittie.
For example: 1 Automoble, It is in Motion, You want to determine, compute, it's speed. (at a particular point and time) A speed measuring device, such as a Radar Speed Gun could be used. As with the Cat, the observation would 'catch' the car in a 'State' that neither at rest or in motion. That done twice, could then determine speed. (*2 & 3)
Catching the light, somewhere along the intended path, or at various points in the path would then observed as a means of computing.
:^0 -d
(*1 in the absence of unknown, or presence of only known factors, computing would un-necessary.)
(*2 you know the time, distance, calulation, to determine the speed)
(*3 the actuall state of the Auto is irrealevent, it of course would be in motion, however, it will be observed at rest, at least twice. Schr?dinger's Car)

by jmgarvin

ARRRGGG! IT HURTS SO MUCH!

So, uh what does this mean for us poor schulbs that don't get it ;-)

by dawgit

poor kitty.
The Cat was in a 'live' state when you put him in the box.
The Cat WILL be dead when you open the box.
No Computing involved. (2 givens)
The real problem is the transition calculation. (What is going on when the Cat is in transition)
a Flux Box. True Quantum Mechanics.

by jaqui

[ I just couldn't resist ]
It's not that hard a concept you know.
You can determine only one point of data with any one observation.

The only thing you can state with any real precision is that point of data, which only applies to the moment of observation.

simple.

by dawgit

"Outside the Box" thinking.
Computing and the related, including software as been still in the '30's/'40's mentality. That is the old Babbage machine gears and pawls, now gates, used by transitors, 1's and 0's.
A seemless flow of light state.... hummmmm
The future might be getting interesting. -d

edited to add:
Jaqui, your "Pipe Dream" might just be very fitting to this whole idea.

by jaqui

the reference.

Here, "pipe dream" means something thought up while stoned on narcotics.
it may be the mental state required to really understand quantum computing though :D

From personal experience, I can attest that it is incredible how seemingly obscure and complex concepts can become so clear and easily grasped while speeding, and so quickly lost again when you've crashed.

[i]Flowers for Algernon[/i] is not wholly fictional.

by jmgarvin

So, what is happening in essence, is that we can never know if the data being observed is the "correct" data?

by deepsand

into a discrete value.

In the case of the quantum spin of an electron, there are only 2 possible values, up or down; i.e., the observed value will be base 2, or binary. There can be no intermediate results.

Hence the name "quantum bit," or "qubit."

I haven't read, or thought of that book in years..... over 30 years ago ?:|
Was at one time, required reading. but then it was the 60's too. :p weeeeeeeeeeeeeee
(hey, wait, that means......... 40 years ago :_| I need more coffee.!. )

by deepsand

in [i]The Magazine of Fantasy & Science.[/i]

It was later adapted for the silver screen, as [i]Charlie[/i] - the 1st, and, I believe only, science fiction movie to capture an Oscar for Best Actor - which then gave birth to the book of the same title, which was then re-titled to that of the original novelette.

Having read the original, and remembering its emotional effect on me, I went to see the movie expecting to be less than satisfied; wow, was I wrong. I was so bummed out that it took quite a long time before I could even speak, let alone move. Being Saturday night, I left the theatre, went to a large and noisy party with countless friends and acquaintences, only to spend the night sitting on the floor lost in reflection.

For your visitation here is the appropriate link to [i]Wikipedia[/i].

This will, of course, require rewriting software to recognize trinary, rather than binary logic: Yes, True and Maybe.

Or not.

by dawgit

I've been thinking of Trinary lately as well. Of course we could just skip to a decinary, but while humanly logical, I don't see any practicality to it. (IMHO)
I think trinary code will be what we will be useing, and rather fast too.
It's good to see others also thinking this way. It is the next logical step.
A Trinary Club on TR, anyone? -d

Quantum Computing was a key component of Michael Chriton's, Timeline novel. It being a requirement for high speed, hyper-parellel processing and data storage to basically record an entire person's body's state for transmission to the earlier time. May understanding was the recording process actually destroyed the person's body, and a completly new one was constructed based on the recorded information. Don't ask me if the 'soul' made the jump, or a new one was created with the new body, or if consciousness or sense of self is just an artifact of our brains.

Come to think of it. Quantum computing would be necessary for Star Trek style transporters to operate too.

by jmgarvin

Doesn't that mean you only have a 50% chance of observing the correct data on a specific atom?

Would the correctness/incorrectness cascade to the other atoms as an effect?

Business' will now expect their employees to be Tritask or Quadtask vs Multitaskable. ;)

With-a-do... many skeptics thought flying or traveling to the moon was a "Pipe Dream". Maybe so: we've bent that pipe too many times to realize we we're counting.

by deepsand

The quantum spin of charged particles or atomic nuclei can be both controlled and observed.

In superconductors, electrons of opposite spins pair up, into what are called Cooper pairs. In so-called high-temperature superconductors, many electrons, of opposite spins, travel about as quasiparticles, equivalent to broken Cooper pairs.

Quasiparticle are, because of the ambiguities of quantum mechanics, 50/50 mixture of particle and non-particle, which is called a hole.

These quasiparticles will, under certain conditions, congregate into clouds of of up-spin and down-spin electrons, with slighty different energies.

The greatest problem currently facing the advancement of quantum computing is how to interact with the qubits so a to be able to both load the initial conditions and read the results without destroying their quantum phase.
