摘要: We investigate constructions for simulating quantum computers with a polynomial slowdown on ensembles composed of qubits which symmetrized versions one- and two-qubit gates can be performed. The simulation is based taking Lie commutators Hamiltonians to extract at desired local positions. During the simulation, only part used storing information, others are left unchanged by commutators. propose various symmetry groups where pretty large fraction used. As few other need set one, our construction requires individual initialization some qubits.
