Material science for quantum computing with atom chips

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