摘要：
Quantum computation requires coherently controlling the evolutions of qubits. Usually, these manipulations are implemented by precisely designing the durations (such as the π-pulses) of the Rabi oscillations and tunable interbit coupling. Relaxing this requirement, herein we show that the desired population transfers between the logic states can be deterministically realized (and thus quantum computation could be implemented) both adiabatically and non-adiabatically, by performing the duration-insensitive quantum manipulations. Our proposal is specifically demonstrated with the surface-state of electrons floating on the liquid helium, but could also be applied to the other artificially controllable systems for quantum computing.
