In spite of the severe restriction, the model can solve several problems (such as calculating Jones polynomials) whose classical efficient solutions are not known. Furthermore, it was shown that if the output probability distribution of the one clean qubit model can be classically efficiently sampled with a constant multiplicative error, then the polynomial hierarchy collapses to the second level.
