I'm not sure that they do resemble a Turing machine. A Turing machine is one that follows a well defined process that could be an infinite number of steps made up of a finite set of symbols. Quantum computing allows for an infinite number of symbols, and doesn't have a well defined process, as it's based on probabilities, not discreet logical operations. Loosely translated, the quantum computer considers all possibilities simultaniously, and incorrect possibilities cancel each other out. The results that are left are the correct possibilities (and any noise).
