Abstract

Trapped ions are one of the leading candidates to realize scalable quantum information processing, where high quality qubits and many of the basic qubit manipulation have been demonstrated. Construction of large-scale quantum computer based on trapped ions faces challenges similar to those faced in the 1940's and 1950's for digital computers: lack of technology platform that will enable large-scale integration of basic logic elements. We will describe a modular and scalable architecture for constructing ion-trap based quantum computer using qubit manipulation techniques that have been demonstrated to date. New integration technologies that will enable higher levels of scalability at all scales of physical hardware implementation will be described, including microfabricated ion traps, MEMS micromirrors for rapid beam steering that enables individual addressing of atomic qubits, and optical components integrated with the microfabricated traps for efficient interaction between ions and photons.
