Universal quantum computation based on nanoelectromechanical systems

We propose to use a buckled plate as qubit, where double-well potential is mechanically produced by pushing the from both sides. The right and left positions of are assigned be quantum states $|0\ensuremath{\rangle}$ $|1\ensuremath{\rangle}$. not gate executed changing buckling force acting on plate, while Pauli-$Z$ phase-shift applying an electric field. A two-qubit materialized with electrostatic potential. They constitute set universal gates. estimate relaxation time coherence time. also discuss fidelity each operation. An examination sample parameters leads feasibility nano-electro-mechanical-system-based computer.
