Fabrication and characterization of nanomechanical properties of double-quantum-dot-based qubits in carbon nanotubes

Abstract

Carbon nanotubes possess quantum properties that make them promising candidates to be used to control and achieve charge qubits. In this paper, we present a remarkable fabrication method to achieve clean low-resistance carbon nanotubes with integrated double quantum dots and a quantum sensor dot. The nanomechanical properties of such a system are studied and a measurement method for detecting single suspended carbon nanotubes in the devices is discussed and efficiently integrated
