Quantum computation is usually performed through optical or magnetic resonance and does not obviously have anything to do with geometry. But, as Lloyd explains in his Perspective, computation can benefit from geometry. He highlights the report by Duan et al., who have found a way to exploit geometry to perform quantum computations more efficiently through sending quantum bits for walks through potential space.
