Would be nice if someone put a more detailed description of Shor's, Steane's, and the 5-qubit codes, as well as possibly Gottesman's stabilizer trickery, together with pretty pictures of quantum circuits. I will try to do that, provided I have enough time. —The preceding unsigned comment was added by 69.156.154.50 (talk • contribs) 03:19, 14 January 2005.

Theoretically, I could add a lot of information here and on the articles for the more important codes. I'm not promising anything, though! Melchoir 02:10, 1 January 2006 (UTC)

[edit] General Question

Can a quantum error code of any variety correct the error in a and b of a qubit a |0> + b |1> ? It doesn't appear that any projective measurement will be able to correct an unknown error in "a". For clarity of the subject, this question ought to be addressed in the article by some expert. Cryptonaut 03:39, 17 April 2006 (UTC)
