Quantum computation is very, VERY exciting, indeed... but I never had the honour to contribute to it. I only volunteered once, in 1997, a course "Quantum information processing" in Tel Aviv University. However, some people cite my course.

[...] continuous parameters, e.g. phase shifts [...] leads to a suspiction that a quantum computer will in fact perform an analog computation, only implemented in a fancy way. A very interesting discussion in [Tsirelson 1997], Lecture 9, convincingly refutes this viewpoint, by displaying those features of quantum computation which distinguish it from both analog and digital classical information processing.
