Microwaving Trapped Ions

Filed under: Uncategorized — rrtucci @ 4:34 pm

The ion trap group at NIST has recently built an ion trap proto-QC that works at microwave frequencies (their old ones worked at optical frequencies and required costly lasers). Their new device is built on a chip and operates at room temperature. It only supports 2 qubits so far though. Pretty exciting and promising, don’t you think?

Check out Chad Orzel’s great blog post about this. It’s always instructive to hear an explanation of an experiment, given by a real experimentalist. Chad Orzel is a Prof of experimental AMO (atomic/molecular/optical) physics at Union College in Schenectady, NY.

My explanation: It’s like a humane version of focusing rays of sunlight on ants. In the humane version, we focus less deadly (?) cell-phone (radar, microwave oven) rays on trapped, yearning to be free, ions. (ions are charged inhabitants of Ionia, a part of ancient Greece.)
