One of the big pushes occuring in ion trap quantum computing these days is the construction of different ion traps which will be useful in scaling up these quantum computer architectures. Chris Monroe’s group at Michigan (in collaboration with Keith Schwab at the PRL in Maryland) has a nice paper out a few days ago in Nature Physics describing a new ion trap they have built (for a news release, see here<\/a>. ) This microtrap is built, basically, on a semiconductor chip, and is of the micrometer size as compared to the millimeter sized traps normally used for trapping ions. Because these traps are fabricated using semiconductor MEMS technology, it is not unreasonable to think of building traps which can stored hundreds to thousands of ions at a time.
\nOne interesting property of the traps described in the paper is the shallow depth of the trapping potential as compared to the depth of the potential for larger, milimeter scale traps (about 0.08 eV in the former compared to order 1 eV in the latter.) What this means is that the ions they trap stay in the trap for minutes as opposed to days, and that it has not been possible to simultaneously trap two ions in the trap. Which is what I love about experiments: while this is an important step, we’re certain to see more steps in the future and it is not unreasonable to expect some good scaling up in of ion trap quantum computers in the next few years.
\nAnother set of experiments involving traps designed to be scalable comes from Isaac Chuang’s group at MIT. A preprint of their work is available as quant-ph\/0511018<\/a>. Me, I just like to flip to the end of their paper and stare at their neat hexagonal trap and dream of the cool things I could do with such a trap.<\/p>\n","protected":false},"excerpt":{"rendered":"
