What is D-Wave's Progress in Quantum Computing?

Click For Summary

Discussion Overview

The discussion centers on D-Wave's claims regarding their advancements in quantum computing, specifically the development of a 16 qu-bit computer and future scalability to 512 and 1024 qu-bits. Participants explore the implications of these claims for the field of quantum computing and compare D-Wave's progress with other research efforts, particularly from NEC in Japan.

Discussion Character

  • Exploratory
  • Debate/contested
  • Technical explanation

Main Points Raised

  • Bertrand introduces D-Wave's claims about their 16 qu-bit computer and future scalability, questioning the credibility of these assertions.
  • ZapperZ provides links to articles discussing D-Wave and mentions a competing claim from researchers in Japan, emphasizing the importance of published research in assessing viability.
  • Bertrand expresses interest in NEC's work and seeks clarification on their qu-bit achievements and future projections, suggesting a potential similarity in principles with D-Wave.
  • Bertrand notes the seriousness of D-Wave's website and their promise of computing power by the end of 2007, indicating anticipation for a significant breakthrough.

Areas of Agreement / Disagreement

Participants express differing levels of confidence in D-Wave's claims versus those of NEC, with no consensus on the credibility of D-Wave's technology or the implications for quantum computing as a whole.

Contextual Notes

There are unresolved questions regarding the specific capabilities of NEC's quantum computing efforts compared to D-Wave's claims, as well as the implications of publication status on the perceived credibility of these technologies.

Who May Find This Useful

Individuals interested in the current state of quantum computing, technological advancements in qu-bit systems, and comparative analysis of competing research efforts in the field.

Hi everybody,

A Canadian company named D-Wave, claims that it has already built a 16 qu-bits computer. This is their website address :

http://dwavesys.com

They also claim the technology they use is "easily" scalable, and they foresee a 512 qu-bits version in the beginning of 2008, and a 1024 qu-bits by the end of 2008.

If their claims are right, it means that quantum computing will be a reality very soon, much earlier in any case than what most specialists used to forecast.

Has anybody heard about this company, and do you know if we can believe them ?

Bertrand

P.S :

maybe this is not the good forum for this topic ?
 
Physics news on Phys.org
I have covered this and also linked to several news reports if you wish to read:

http://physicsandphysicists.blogspot.com/2007/04/even-more-review-of-that-quantum.html

NOt only that, recently, researchers in Japan have made another claim of a key step towards a quantum computer, and this time, they actually published the physics of the system that many consider to be more viable (and certainly, testable), something D-Wave has no intention of doing.

OK, Thank you, ZapperZ !

I have read your articles. Unfortunately, I could not get the article from the NEC people.

You seem to be more confident in NEC, mainly because they published ?

How many qu-bits could NEC obtain, and what do they forecast for the future ?

From what I understand, they use similar principles as D-Wave ?

I read through D-wave website.

The thing seems really serious. They say they will provide computing power by the end of 2007. They also provide quite an elaborate API.

I don't think this could be a mystification. Within 6 months, we should know if we are living a true revolution or not.
