Electric circuits for universal quantum gates and quantum Fourier transformation
A set of universal quantum gates can be constructed based on quantum walk by formulating it as a scattering problem on a graph. In this paper, we simulate quantum gates by electric circuits, following a recent report that a one-dimensional LC electric ...
