Spurious References
[edit]There are several references to papers by I. C. Baianu. They are listed as having been published in 1971, but they were clearly written much later, and date from 2004. There are no references in the existing literature to this work outside of the author's own papers.
On further inspection, I. C. Baianu appears to be a professor of Food Chemistry, and has no affiliations with any research groups in physics, mathematics, or computer science. This is highly unusual for someone claiming to have produced work in the field of Quantum Computation that would have been decades ahead of it's time.
The papers themselves are largely incoherent, with meaningless jargon throughout. —Preceding unsigned comment added by 90.197.152.10 (talk) 12:32, 28 November 2009 (UTC)
- Baianu really was publishing as early as 1971; see e.g. doi:10.1007/BF02476778. But I can easily believe (just from seeing the first page of that reference) that his works are buzzword-laden nonsense rather than containing any substantive contribution. Thanks for catching this. —David Eppstein (talk) 18:24, 28 November 2009 (UTC)

| It seems to me that this article needs substantial revision.
The introduction to the article does not appear to refer to Quantum Cellular Automata in any way --- not for that matter, to quantum mechanics, quantum computing, or cellular authomata, which are the concepts which are typically combined to arrive at the notion of quantum cellular automata. The next section is effectively a stub article on Cellular Automata (though to be fair, that article is linked to by this article). It would be preferable to give a description of the concept of quantum cellular automata in general, and restrict discussion to comparisons with (classical) cellular automata. The rest of the article seems to consist of a long and involved description of a single proposal for implementing quantum cellular automata --- which by this point in the article is still an undefined term --- with quantum dots. On this, I am not competent to comment. However, this domination by a single proposal for an implementation is unfortunate for people who might visit this page to find out about computational models of QCA, such as the models introduced by John Watrous [1], Benjamin Schumacher and Reinhard Werner [2], or Carlos Perez-Delgado and Donny Cheung [3]. In short, it would be preferable if this article actually defined and/or discussed the concept of quantum cellular automata in general, describing parallels and differences from the traditional theory of cellular automata; specifically, it should not be concentrated on any single proposal.
