High-Fidelity Universal Set of Quantum Gates using Non-adiabatic Rapid Passage

Numerical simulation results are presented which suggest that a class of non-adiabatic rapid passage sweeps known as twisted rapid passage should be capable of implementing a universal set of quantum gates that operate with high fidelity. The universal set consists of the Hadamard and NOT gates, together with variants of the phase, pi/8, and controlled-phase gates. The simulations suggest that the universal set of gates produced by twisted rapid passage shows promise as possible elements of a fault-tolerant scheme for quantum computing.
