Article seems to fail both WP:NOTESSAY and possibly also WP:GNG. It does not really define its apparent topic, although it seems to be about the application of quantum computing to continous problems. I do not think the phrase "continuous quantum computing" is in common parlance with this meaning, however. The sources provided are applications of quantum computing to continuous rather than discrete problems; however I don't think they establish notability of this concept or phrase- none that I checked mention "continuous quantum computation" or any variant thereof.

I would tend to agree- although I would suggest that the amount of useful material on the page as it currently stands is absolutely minimal. I don't think personally that every project given a funding grant is notable, also. Porphyro (talk) 14:06, 4 May 2017 (UTC)[reply]
Fully agree with you. prokaryotes (talk) 14:36, 4 May 2017 (UTC)[reply]

  • Delete per WP:NOTESSAY. This appears to be a personal essay on the topic. I'm not sure anything here is salvageable for our purposes. Continuous quantum computation may be a sufficiently notable topic for an article (unclear to me), but I think WP:TNT may be appropriate here. Ajpolino (talk) 16:11, 8 May 2017 (UTC)[reply]
  • Keep – I wrote a new lede (brief, but better than the cold open that was there before), and I condensed and reorganized the existing text so that it reads more like an article than an essay. The subject is definitely worth covering; one review by Braunstein and van Loock alone has 1350 citations in the Web of Science (and over two thousand citations by the more relaxed standards of Google Scholar).

A comment- I think your lede is at odds to what the original article is supposed to be about. The article, and all its examples that I have checked, are about the application of regular quantum computing with a finite quantum dimension to problems that have a continous "flavour". The only source that uses the title phrase "continuous quantum computation" is the Columbia grant page, and if you check the list of publications there, they are about digital quantum computation. Given that "continuous quantum computation" is not a phrase in regular usage, I would suggest that an article under that name, with the lede you have provided, is not tenable. I have reverted your edits- though I believe they would be a good start for a page called "Quantum information with continuous variables" or the like. Porphyro (talk) 18:04, 9 May 2017 (UTC)[reply]
Fine. Informally polling colleagues, it seems that the sense of "continuous" used by the original article is significantly less common than the Braunstein–Lloyd–van Loock–etc. sense. (If anyone is curious, I have a draft of "Continuous-variable quantum computation" here.) XOR'easter (talk) 18:41, 9 May 2017 (UTC)[reply]
One confusing thing is that the final reference (Adesso, G., Ragy, S. and Lee, A. R. (2014), Continuous variable quantum information: Gaussian states and beyond, arXiv:1401.4679) is very definitely about the infinite-Hilbert-space-dimension sense. So, this article has been somewhat of a blend since (...checks history...) 2014. I take this to suggest that it might be better to start from scratch. XOR'easter (talk) 19:39, 9 May 2017 (UTC)[reply]
Having gone over the article again, editing it for encyclopedic tone and so forth, I think the best course of action would either be to move it to something like "Quantum computation of continuous functions", or to merge it into an appropriate article (like quantum computation, as suggested above). There does appear to be a legitimate literature on this general area, but the current name for the article is quite confusing, and it is possible that there simply isn't enough article here to stand on its own. XOR'easter (talk) 21:14, 9 May 2017 (UTC)[reply]
I tend to agree with your colleaagues that I would have associated the title with the continuous variables rather than the- actually slightly nebulous idea- of computation of continuous functions, so I would definitely agree that the page should be moved to a more appropriate title if kept. I agree that there is literature on this point, but I'm questioning whether or not it's a useful distinction- to make a slightly frivolous illustration it seems a little like having an article called "Scientists whose names contain only letters from the first half of the alphabet". It contains noteworthy subjects but the classification isn't itself of much note. Thank you for your work improving the article- even if the consensus is for deletion I think we can merge some of this content into quantum computation.
