I recently read a paper, published last year, which suggests that the qubit concept is problematic and that a different processing model is needed for quantum computing: On The Fundamental Flaws of Qubit Concept for General Purpose Quantum Computing http://www.ijesi.org/papers/Vol%283%2910/F031059070.pdf http://www.ijesi.org/papers/Vol%283%2910/F031059070.pdf See also: Quantum computing circuits http://www.google.com/patents/US20130057314 http://www.google.com/patents/US20130057314
