Abstract

In its most general form, the atom chip is a device in which neutral or charged particles are positioned in an isolating environment such as vacuum (or even a carbon solid state lattice) near the chip surface. The chip may then be used to interact in a highly controlled manner with the quantum state. I outline the importance of material science to quantum computing (QC) with atom chips, where the latter may be utilized for many, if not all, suggested implementations of QC. Material science is important both for enhancing the control coupling to the quantum system for preparation and manipulation as well as measurement, and for suppressing the uncontrolled coupling giving rise to low fidelity through static and dynamic effects such as potential corrugations and noise. As a case study, atom chips for neutral ground state atoms are analyzed and it is shown that nanofabricated wires will allow for more than 104 gate operations when considering spin-flips and decoherence. The effects of fabrication imperfections and the Casimir–Polder force are also analyzed. In addition, alternative approaches to current-carrying wires are briefly described. Finally, an outlook of what materials and geometries may be required is presented, as well as an outline of directions for further study.

  70. It should be noted that considering the noise only at the trap center (as usually done) may not be sufficient, as by doing so one neglects the fact that the trap is commonly spatially inhomogeneous (e.g. harmonic). The atoms are distributed in the trap with a certain density profile, and move as they have finite temperature. Taking this into account introduces corrections to the theory which in some cases may be important
