Quantum Electro-Mechanical Systems - Recipe to make a mechanical device interfere with itself

Abstract

A dominant theme of modern physics is to show that quantum mechanics is a valid description of the world, from atomic lengths scales and upward. This pursuit is aimed at both answering questions about the apparent boundary between the classical and quantum world, and at exploiting quantum behavior for technological purpose. As a result of the intense effort in quantum computing, nano-electronic devices have entered this realm and shown themselves to be fully quantum mechanical. Single electron devices and SQUIDs have recently exhibited quantized energy levels, Schrodinger evolution, and superposition states (Nakamura et al., 1999; Friedman et al., 2000; Vion et al., 2002).
