[edit] Subdivisions: Months, theory/experiment, etc.

This page offers a good insight into the development of quantum computing. However, there's quite a bit missing, especially in terms of recent developments - too much has happened in the last 10 years or so, in order to be able to provide a good overview by merely dividing by year. Too many events, often not related to each other, get put into a single long paragraph. From some point onward (1995 for example), I suggest sorting milestones by month of the year.

Another suggestion, as quantum computing is such a multi-disciplinary field, would be to divide developments into their respective disciplines. For example, developments in theory (e.g. error correction), could be separated from experimental ones (e.g. multiple qubit entanglement). I'm not suggesting a separate timeline (that would detract from the idea that quantum computing unifies many fields), just maybe a more intuitive subdivision than the monthly one I suggested above.

In any case, this page has a lot of potential, but as it stands, I don't think it has the scalability, and more importantly the readability it deserves. In case there are no objections, I'll try to reorganize it. Tomatoman 20:10, 6 January 2006 (UTC)

Just realized the obvious solution that was escaping me - for every year just have all the developments bullet-pointed in chronological order. Will get this done as soon as I've got a moment. Tomatoman 21:03, 7 January 2006 (UTC)

There are too many entries in 2005 and 2006. Many of these are just theoretical proposals and their merit is still unclear. I think this page should only include acknowledged milestones. --J S Lundeen 18:50, 8 March 2006 (UTC)

[edit] Feynman 1981

"However, instead of viewing this intractability as an obstacle, Feynman regarded it as an opportunity. He pointed out that if it requires that much computation to work out what will happen in a multi-particle interference experiment, then the very act of setting up such an experiment and measuring the outcome is equivalent to performing a complex computation."

Does the information contained in the above quotation not appear in the International Journal of Theoretical Physics article describing his talk? I just read the paper, have it in front of me, and was looking for any mention of Feynman viewing this as an opportunity. What I found is section 4: QUANTUM COMPUTERS -- UNIVERSAL QUANTUM SIMULATORS. There he does not talk about how setting up this experiment is equivalent to performing a complex computation; he restricts his view of a quantum computer to a machine capable of simulating physical laws. Am I wrong? Does the idea of measurement being equivalent to complex computation show up somewhere in this paper, or does it do so elsewhere? Ruberik 21:01, 16 June 2006 (UTC)

I am having trouble with my citating the Oct 4 06 article. Could you help?

[edit] Reverse-chronological order

Shouldn’t this be in reverse-chronological order?! Can I go ahead and change it? --V4vijayakumar 06:58, 25 October 2006 (UTC)

[edit] 2006

is fact that just the previous year takes up almost half the timeline a reflection of acceleration of progress?--87.65.167.243 16:54, 29 November 2006 (UTC)

Partially, but there's definitely a lot of spam in there. Most of the events are just headlines that have been copied and pasted. I mean, come on! There's no way "Electrons interacting with individual dopant atoms in silicon observed, a step to silicon based quantum computers." or "Entire history of single photon observed." or "New material proposed for quantum computing." belong there, at least not in that kind of wording. We really need an expert to (1)weed out the junk and (2) explain this stuff more meaningfully. Tcamps42 04:34, 23 May 2007 (UTC)

Maybe you are right, but when I check these sources they all conform to the development of quantum computers and so are fit into the timeline. However, I tought of the idea of renaming the article from 'Timeline of quantum computing' into 'Timeline of development in quantum computing.' The reason because the whole article is only pointing out events in development. Reallife quantum computers have not been realised up to this time of writing. ;)

[edit] source?

It looks like a partly c/p from thocp - quantum computers

[edit] Quantum time bomb

"2002 - 11th UK conference on the Foundations of Physics, the Philosophy Centre, University of Oxford, September 9 - 13 sees the exposition of the theory of the Quantum Time Bomb."

The theory of what? I don't know anything about quantum computing, normal bits are quite enough for me thanks, but this theory sounds like it's part of Quantum bogodynamics, and I think it just broke my bogon meter. Many of the very few hits I get on Google are about something called "Harry Potter and the Quantum Time Bomb"[1]. Is this really something serious and notable or just a joke? -- Coffee2theorems 15:40, 15 June 2007 (UTC)

I'm familiar with quantum computing and I haven't heard of "Quantum Time Bomb". It's certainly not notable nearly the same degree as the other things listed for 2000-2004 and it may even be a joke. I'm removing it. If anyone puts it back, they should provide an explanation. Andris 21:07, 15 June 2007 (UTC)

[edit] Roman Ingarden

Link to Roman Ingarden in this article is improper - the physycist involved was a son of Roman Ingarden, namely Roman Stanisław Ingarden. There isn't an article about him on English wiki however. See: pl:Roman Stanisław Ingarden. —Preceding unsigned comment added by 83.8.124.165 (talk) 12:49, 17 September 2007 (UTC)
